The Analysis About Seepage And Stress Coupling Of The Bank Slope Under The Cycle Of Water Lifting And The Study Of Stability

Recently, There are many the large Water conservancy and Hydropower Engin-eerings in china.As The Three Gorges project in changjiang,XiaoLangDi Water Control Project in Yellow River Water,South-North Diversion Project and it opened the heart of china’s Sinohydro chapter,Laid asolid foundation for China’s economic construction and social sustainable development,has occurred at the same time produce reservoir bank stability,bank collapses,sliding accident,endangering downstream of the dam and the people’s life and property safety,China’s annual economic losses due to landslides caused by from time to estimate;therefore depth of the reservior shore the slope deformation features and the main factors is crucial for bank slope stability evaluation,to ensure the normal operation of the reservior,to maintain the healthy life of rivers is siqnificant.The chapter is based on the monitoring results which is from the indoor slope test in the Yellow River Water Research Institute, according to#1slope of Xiaolangdi in Yellow River Water, analyses the coupling of slope’ seepage field and stress field in the water level repeated fluctuation role and slope safety factor;The main work and conclusions in this dissertation are as follows:(1) Based#1slope of Xiaolangdi in Yellow River and similarity theory, slope model indoor conducted a comprehensive simulation; Based the saturated-unsaturated theoretical. The chapter simulates the slope’ seepage field in three times the water level circulation lift using GeoStudio:(2) Combined with the theory of fluid-structure interaction, this paper analyses the law of slope’ pore water pressure in the water level under the action and deformation characteristics with Seep/w and Sigma/w software;(3) According to the results from the monitoring of indoor, compared with the results of finite element analysis;(4) Based on Visual2005C#development platform, combined the Matlab and Excel Slope/w has secondary development, research slope safety factor variation;...
