| 1 | Studies on the evolution process of rockbursts in deep tunnels显示文摘This paper focuses on the evolution processes of different types of rockbursts occurring in deep tunnels. A series of laboratory tests and in-situ monitoring in deep tunnels excavated by tunnel boring machine (TBM) and drill-and-blast (D&B) method have been conducted to understand the mechanisms and processes of the evolution of different types of rockbursts, including strain rockburst, strain-structure slip rockburst, immediate rockburst and time-delayed rockburst. Three different risk assessment methods are proposed to evaluate the intensity and potential failure depth of rockbursts. These methods can be applied before excavation and the results can be updated according to the real-time information during excavation. Two micro-seismicity based real-time warning systems have been established for predicting various intensities of rockbursts, such as slight, moderate, intensive and extremely intensive rockbursts. Meanwhile, the probability and intensity of the rockburst are also given. The strategy for excavation and support design has been suggested for various intensities of rockbursts before excavation. The strategy for dynamic control of the rockburst evolution process is also proposed according to the monitoring results. The methodology has been successfully applied to rockburst risk reduction for deep tunnels at Jinping II hydropower project. The results have illustrated the applicability of the proposed methodology and techniques concerning rockbursts. | Xiating Feng Bingrui Chen Shaojun Li Chuanqing Zhang Yaxun Xiao Guangliang Feng Hui Zhou Shili Qiu Zhouneng Zhao Yang Yu Dongfang Chen Huajun Ming | 2012 | Journal of Rock Mechanics and Geotechnical Engineering2012，4，4： | 11 |

| 3 | An operating state estimation model for integrated energy systems based on distributed solution显示文摘In view of the disadvantages of the traditional energy supply systems,such as separate planning,separate design,independent operating mode,and the increasingly prominent nonlinear coupling between various subsystems,the production,transmission,storage and corn sumption of multiple energy sources are coordinated and optimized by the integrated energy system,which improves energy and infrastructure utilization,promotes renewable energy consumption,and ensures reliability of energy supply.In this paper,the mathematical model of the electricity-gas interconnected integrated energy system and its state estimation method are studied.First,considering the nonlinearity between measurement equations and state variables,a performance simulation model is proposed.Then,the state consistency equations and constraints of the coupling nodes for multiple energy sub-systems are established,and constraints are relaxed into the objective function to decouple the integrated energy system.Finally,a distributed state estimation framework is formed by combining the synchronous alternating direction multiplier method to achieve an efficient estimation of the state of the integrated energy system.A simulation model of an electricity-gas interconnected integrated energy system verifies the efficiency and accuracy of the state estimation method proposed in this pape.The results show that the average relative errors of voltage amplitude and node pressure estimated by the proposed distributed state estimation method are only 0.0132%and 0.0864%,much lower than the estimation error by using the Lagrangian relaxation method.Besides,compared with the centralized estimation method,the proposed distributed method saves 5.42 s of computation time.The proposed method is more accurate and efficient in energy allocation and utilization. | Dengji ZHOU Shixi MA Dawen HUANG Huisheng ZHANG Shilie WENG | 2020 | Frontiers in Energy2020，14，4： | 5 |
| 4 | A local homogenization approach for simulating the reinforcement effect of the fully grouted bolt in deep underground openings显示文摘Fully grouted bolts are a key component of the support system for underground openings.Although considerable effort has been made in the simulation of the reinforcement effect of the fully grouted bolts on the rock masses surrounding underground openings,most of the work has limited significance since the structural element approach is used.This study proposes a local homogenization approach(L-H approach)that integrates elastoplastic mechanics,composite mechanics,and analytical approaches with numerical simulation to effectively simulate the reinforcement effect of the fully grouted bolt on deep surrounding rock masses.In the L-H approach,the representative volume of bolted rock mass(RVBRM)with a fully grouted bolt is established based on the original mesh model utilized in the rockbolt element approach.The RVBRM is a regular quadrangular prism with a cross-sectional size equal to the bolt spacing and a length equal to the bolt length.The RVBRM is homogenized by the L-H approach from a unidirectional bolt-reinforced composite into a homogeneous transversely isotropic medium whose mechanical properties are described by a new transversely isotropic elastoplastic model.The L-H parameters for the RVBRM are obtained using analytical approaches,composite mechanics,and known parameters of the rock mass and bolt.Using the L-H approach,the reinforcement effect of the fully grouted bolt on the bolted rock specimen and the surrounding rock mass in Jinping II Diversion Tunnel#2 with a depth greater than 2000 m is simulated.The results show that the predictions of the L-H approach are more in agreement with the physical model results of bolted rock specimen and provide a more realistic response of the bolted surrounding rock mass.The L-H approach demonstrates that fully grouted bolts with common bolt spacings and diameters substantially enhance the elastic modulus,shear strength,and tensile strength of the rock mass in the direction of the bolt axis. | Dingping Xu Xiuyang Liu Quan Jiang Shaojun Li Yangyi Zhou Shili Qiu Fei Yan Hong Zheng Xiang Huang | 2022 | International Journal of Mining Science and Technology2022，32，2： | 3 |
| 5 | A modified highly precise direct integration method for a class of linear time-varying systems显示文摘It is always a bottleneck to design an effective algorithm for linear time-varying systems in engineering applications.For a class of systems,whose coefficients matrix is based on time-varying polynomial,a modified highly precise direct integration(VHPD-T method)was presented.Through introducing new variables and expanding dimensions,the system can be transformed into a timeinvariant system,in which the transfer matrix can be computed for once and used forever with a highly precise direct integration method.The method attains higher precision than the common methods(e.g.RK4 and power series)and high efficiency in computation.Some numerical examples demonstrate the validity and efficiency of the method proposed. | LIU XiaoMei ZHOU Gang ZHU Shuai WANG YongHong SUN WeiRong WENG ShiLie | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，7： | 3 |
| 6 | Decoupling optimization of integrated energy system based on energy quality character显示文摘Connections among multi-energy systems become increasingly closer with the extensive application of various energy equipment such as gas-fired power plants and electricity-driven gas compressor.Therefore,the integrated energy system has attracted much attention. This paper establishes a gas-electricity joint operation model,proposes a system evaluation index based on the energy quality character after considering the grade difference of the energy loss of the subsystem,and finds an optimal scheduling method for integrated energy systems.Besides,according to the typical load character- istics of commercial and residential users,the optimal scheduling analysis is applied to the integrated energy system composed of an IEEE 39nodes power system and a 10nodes natural gas system.The results prove the feasibility and effectiveness of the proposed method. | Shixi MA Shengnan SUN Hang WU Dengji ZHOU Huisheng ZHANG Shilie WENG | 2018 | Frontiers in Energy2018，12，4： | 3 |
| 7 | Expression and Purification of Enterovirus Type 71 Polyprotein P1 using Pichia pastoris system显示文摘Enterovirus type 71(EV71) causes severe hand-foot-and-mouth disease(HFMD) resulting in hundreds of deaths of children every year;However,currently,there is no effective treatment for EV71.In this study,the EV71 poly-protein(EV71-P1 protein) gene was processed and cloned into the eukaryotic expression vector pPIC9k and then expressed in Pichia pastoris strain GS115.The EV71 P1 protein with a molecular weight of 100 kD was produced and secreted into the medium.The soluble EV71 P1 protein was purified by column chromatography with a recovery efficiency of 70%.The result of the immunological analysis showed that the EV71 P1 protein had excellent immunogenicity and could stimulate the production of EV71-VP1 IgG antibody in injected rabbits.We suggest that EV71-P1 protein is an ideal candidate for an EV71 vaccine to prevent EV71 infection. | Xue Han Xiaoling Ying Hao Huang Shili Zhou Qi Huang | 2012 | Virologica Sinica2012，27，4： | 2 |
| 8 | Experimental research of condensate blockage and mitigating effect of gas injection显示文摘The condensate blockage causes a substantial decrease in well productivity for gas condensate reservoirs.Based on the previous studies,a novel experimental method was designed to evaluate condensate blockage and the mitigating effect of gas injection.The method considers the stacking effect in the near wellbore region and the gas flow in the far wellbore region.There is an intermediate vessel containing condensate gas at the entrance of core holder in the experimental apparatus.In the process of pressure depletion experiment in a long core model,the vessel is connected to the core and the pressure of the vessel remains above the dew point pressure.The seriousness of condensate blockage is investigated by this research.When pressure drops to maximum retrograde condensation pressure,the gas permeability decreases by 80%compared with the initial gas permeability.Contrastive experiments were conducted to study the removal effect of different injection fluids and different injection volumes.The results show that CO2 injection is more effective than methanol in mitigating condensate blockage and the optimal CO2 injection volume is around 0.15 HCPV。 | Zhouhua Wang Shili Zhu Wei Zhou Huang Liu Yisheng Hu Ping Guo Jianfen Du Junjie Ren | 2018 | Petroleum2018，4，3： | 2 |

| 19 | Distal axis sulfide mineralization on the ultraslow-spreading Southwest Indian Ridge:an LA-ICP-MS study of pyrite from the East Longjing-2 hydrothermal field显示文摘The newly discovered East Longjing-2 hydrothermal field(ELHF-2)is located on the Dragon Horn oceanic core complex of the ultraslow-spreading Southwest Indian Ridge,approximately 12 km from the ridge axis.This study measured the chemical compositions of pyrite from ELHF-2 using a laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS)to investigate the genesis of the field.Three generations of pyrite were classified,and found that:Py1 and Py2,rich in V,Mn,U,and Se,occur in altered basalt debris and the silica alteration matrix,respectively.Py3 was mainly intergrown with chalcopyrite in quartz veins and had higher Cu,In,Ag,Sb,and Au contents than Py1 and Py2.Some elements,such as Au,Se,and Pb,are likely presented as direct substitution with Fe^(2+)in pyrite,while Cu,Zn,Co,Ni,and Ag probably occur both as direct substitution with Fe and as distributed micro-to nanoparticle-sized sulfides.Meanwhile,the occurrence of V,Mn,and U is likely presented as oxide inclusions.Trace element geochemistry suggested that the pyrite was formed under hightemperature conditions,and the ore forming elements were likely derived from ultramafic rocks.In addition,Py1and Py2 were formed under higher water/rock ratio and higher temperature conditions,with more seawater involvement compared with Py3.The formation of ELHF-2 was probably driven by exothermic serpentinization reactions with an additional magmatic heat.This study shows that high-temperature hydrothermal circulation driven by magmatic activity can be developed on distal rift flank areas of magma-starved ultraslow-spreading ridges. | Shili Liao Chuanwei Zhu Jianping Zhou Weiyong Liu Junyu Yu Jin Liang Weifang Yang Wei Li Jia Liu Chunhui Tao | 2021 | Acta Oceanologica Sinica2021，40，5： | 1 |
