| 1 | A new procedure to estimate the rainfall erosivity factor based on Tropical Rainfall Measuring Mission(TRMM) data显示文摘Soil erosion by water is the most important land degradation problem worldwide.In this paper a new procedure was developed to estimate the rainfall-runoff erosivity factor(R)based on Tropical Rainfall Measuring Mission(TRMM)satellite-estimated precipitation data,which consists of 3-h rainfall intensity data.In this method,R was calculated as the product of the maximum 180-min rainfall intensity and the rainfall energy.This procedure was applied to the Daling River basin in Liaoning Province,China,R in terms of yearly,monthly and event-based rainfall in 2005 was computed separately using TRMM 3B42 data.The TRMM data showed a significant correlation with the interpolated rain-gauge data.Furthermore,because the TRMM data are based on rainfall intensity,they can represent the impact on erosion more accurately.It reflects both the spatial distribution and the intensity of rainfall.The procedure is a new approach to estimate the rainfall erosivity for soil water erosion modeling,especially in areas lacking rain-gauge stations. | ZHU Qiang CHEN XiuWan FAN QiXiang JIN HePing LI JiRen | 2011 | Science China(Technological Sciences)2011，54，9： | 15 |
| 2 | Optimization design of foundation excavation for Xiluodu super-high arch dam in China显示文摘With better understanding of the quality and physico-mechanical properties of rocks of dam foundation,and the physico-mechanical properties and structure design of arch dam in association with the foundation excavation of Xiluodu arch dam,the excavation optimization design was proposed for the foundation surface on the basis of feasibility study.Common analysis and numerical analysis results demonstrated the feasibility of using the weakly weathered rocks III1and III2as the foundation surface of super-high arch dam.In view of changes in the geological conditions at the dam foundation along the riverbed direction,the design of extending foundation surface excavation area and using consolidating grouting and optimizing structure of dam bottom was introduced,allowing for harmonization of the arch dam and foundation.Three-dimensional(3D)geomechanics model test and fi nite element analysis results indicated that the dam body and foundation have good overload stability and high bearing capacity.The monitoring data showed that the behaviors of dam and foundation correspond with the designed patterns in the construction period and the initial operation period. | Qixiang Fan Shaowu Zhou Ning Yang | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，2： | 6 |
| 3 | Monitoring result analyses of high slope of five-step ship lock in the Three Gorges Project显示文摘The construction of the double-lane fi ve-step ship lock of the Three Gorges Project(TGP)was commenced in 1994,the excavation of the ship lock was completed by the end of 1999,and the ship lock was put in operation in June 2003.The side slopes of the ship lock are characterized by great height(170 m),steepness(70 m in height of upright slope),and great length(over 7000 m in total length).In association with the ship lock,the surrounding rocks in slope have a high potential to deform,with which the magnitude of deformation is restricted.Monitoring results show that the deformation of the fi ve-step ship lock high slopes of the TGP primarily occurred in excavation period,and deformation tended to be stable and convergent during operation period,suggesting the allowable ranges of deformation.At present,the slopes and lock chambers are stable,and the ship lock works well under normal operation condition,enabling the social and economic bene fi ts of the TGP. | Qixiang Fan Hongbing Zhu Jun Gen | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，2： | 4 |
| 4 | Unloading performances and stabilizing practices for columnar jointed basalt:A case study of Baihetan hydropower station显示文摘The columnar jointed rock mass(CJR), composed of polygonal cross-sectional columns cut by several groups of joints in various directions, was exposed during the excavations of the Baihetan hydropower station, China. In order to investigate the unloading performances and the stability conditions during excavation of the columns, an experimental field study was performed. Firstly, on-site investigations indicated that the geotechnical problems, including rock relaxation, cracking and collapse, were the most prominent for the CJR Class I that contains intensive joint network and the smallest column sizes.Comprehensive field tests, including deformation measurement by multi-point extensometers, ultrasonic wave testing, borehole television observation and stress monitoring of rock anchors, revealed that the time-dependent relaxation of the CJRs was marked. The practical excavation experiences for the Baihetan columnar jointed rock masses, such as blasting scheme, supporting time of shotcrete and rock bolts, were presented in the excavations of the diversion tunnels. These detailed investigations and practical construction experiences can provide helpful information for similar geotechnical works in jointed rock mass. | Qixiang Fan Xiating Feng Wenlin Weng Yilin Fan Quan Jiang | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，6： | 4 |
| 5 | Hot Corrosion Behavior of a Cr-Modified Aluminide Coating on a Ni-Based Superalloy显示文摘A Cr-modified aluminide coating is prepared on a Ni-based superalloy using arc ion plating and subsequent pack cementation aluminizing.Hot corrosion behavior of the Cr-modified aluminide coating exposed to molten Na2SO4/K2SO4(3:1) or Na2SO4/NaCl(3:1) salts at 900 °C in static air are evaluated as well as the aluminide coating.The results indicate that compared with the aluminide coating,the anti-corrosion properties of the Cr-modified aluminide coating in the both salts are improved,which should be attributed to the beneficial effect of the Cr in the coating.The corrosion mechanism of the Cr-modified aluminide coating,especially the role of Cr in the mixture salt corrosion,is discussed. | Duoli Wu Sumeng Jiang Qixiang Fan Jun Gong Chao Sun | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 4 |
| 6 | Key technologies for the construction of the Xiluodu high arch dam on the Jinsha River in the development of hydropower in western China显示文摘Hydropower development in China is concentrated in the country's western regions.Among all the rivers in China,the lower course of the Jinsha River contains the richest hydro-energy resource,and therefore,4 mammoth hydropower plants are under construction on this particular section of the river at Wudongde,Baihetan,Xiluodu,and Xiangjiaba.The water-blocking structures of the hydropower facilities at Wudongde,Baihetan and Xiluodu are all arch dams of around 300 m high.In view of changes in the geological conditions at the foundation of the Xiluodu dam on the riverbed after excavation started,the designs of expanding foundation surface excavation and dovetailing the dam body and foundation rock on both upstream and downstream sides were introduced,allowing the arch dam and foundation to fit each other and improving the stress conditions of the dam body and foundation.By dividing the dam body into various concrete sections,the dynamic properties of concrete were adequately adjusted to the distribution of stress in the dam body.In addition,the use of the most optimal concrete material and mixture ratio allowed thermodynamics of concrete to satisfy the requirements of the strength,durability,temperature control and crack prevention of the concrete.Moreover,rigorous temperature control measures were introduced to prevent harmful cracking,thus enhancing the integrity of the arch dam.Furthermore,sophisticated construction machinery,scientific testing methods,and sound construction techniques were employed to ensure the uniformity and reliability of concrete placement.The 'Digital Dam' for the Xiluodu project,which is based on the theory of total life cycle,has supplied strong support for construction process control and decision-making. | Lu Youmei Fan Qixiang Zhou Shaowu Li Bingfeng Li Wenwei | 2012 | Engineering Sciences2012，10，2： | 3 |

| 13 | Molecular Mechanisms of Lymphocyte-Mediated Cytotoxicity显示文摘Granule-mediated cytotoxicity is the major mechanism for lymphocytes to kill viruses, intracellular bacteria and tumors. The cytotoxic granules move to the immunological synapse by exocytosis after recognition of a killer cell.The contents of the granules are delivered into target cells with the help of perforin by endocytosis. A group of serine protease granzymes cleave their critical substrates to initiate DNA damage and cell death. The most abundant granzymes are granzyme A and B. They induce cell death through alternate and nonoverlapping pathways. The substrates and functions of the majority of the orphan granzymes have not yet been identified. It is possible that the diversity of granzymes provides fail-safe mechanisms for killing viruses and tumor cells. | Zusen Fan Qixiang Zhang | 2005 | Cellular & Molecular Immunology2005，2，4： | 1 |
