| 1 | Review of collapse triggering mechanism of collapsible soils due towetting显示文摘Loess soil deposits are widely distributed in arid and semi-arid regions and constitute about 10% of land area of the world.These soils typically have a loose honeycomb-type meta-stable structure that is susceptible to a large reduction in total volume or collapse upon wetting.Collapse characteristics contribute to various problems to infrastructures that are constructed on loess soils.For this reason,collapse triggering mechanism for loess soils has been of significant interest for researchers and practitioners all over the world.This paper aims at providing a state-of-the-art review on collapse mechanism with special reference to loess soil deposits.The collapse mechanism studies are summarized under three different categories,i.e.traditional approaches,microstructure approach,and soil mechanics-based approaches.The traditional and microstructure approaches for interpreting the collapse behavior are comprehensively summarized and critically reviewed based on the experimental results from the literature.The soil mechanics-based approaches proposed based on the experimental results of both compacted soils and natural loess soils are reviewed highlighting their strengths and limitations for estimating the collapse behavior.Simpler soil mechanics-based approaches with less parameters or parameters that are easy-to-determine from conventional tests are suggested for future research to better understand the collapse behavior of natural loess soils.Such studies would be more valuable for use in conventional geotechnical engineering practice applications. | Ping Li Sai Vanapalli Tonglu Li | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，2： | 15 |
| 2 | VM液氦温区制冷机中热压缩机性能的数值模拟与实验研究显示文摘对无负载热压缩机进行了数值模拟及实验研究,计算与实验结果表明,无负载情况下热压缩机所获得的压比主要受频率、排出器位移(即扫气量)和冷端温度的影响。排出器位移越大,压比越高;冷端温度越低,压比越高。在现有实验条件下,热压缩机工作在3 Hz时能够获得较高压比,其中排出器位移为6.0 mm时,可以获得的最高压比为1.3。计算结果与实验结果的对比表明两者能够较好吻合。 | 赵月晶 王晓涛 戴巍 S Vanapalli 陈燕燕 罗二仓 | 2015 | 低温工程2015，，6： | 5 |
| 3 | Review of methods for predicting in situ volume change movementof expansive soil over time显示文摘The soil movement information over time is required for the design of foundations placed in expansive soils. This information is also helpful for the assessment of pre-wetting and controlled wetting mitigation alternatives for expansive soils. Several researchers during the past fifteen years have proposed different methods for the prediction of the soil movements over time. The available methods can be categorized into(i) consolidation theory-based methods,(ii) water content-based methods, and(iii) suction-based methods. In this paper, a state-of-the-art of the prediction methods is succinctly summarized. The methods are critically reviewed in terms of their predictive capacity along with their strengths and limitations. The review highlights the need for prediction methods that are conceptually simple yet efficient for use in conventional engineering practice for different types of expansive soils. | Hana H.
