西藏某水电站左岸坝肩边坡地震稳定性分析
Analysis on the seismic stability of left abutment slope of a hydropower station in Tibet
摘要
Abstract
The stability of rock slope under the effect of earthquake plays a significant role in slope stability study, which is difficult to analyze. The paper, based on the engineering geological conditions in the area where the hy-dropower station is to be located, analyzed the dynamic stability of the slope in combination with engineering ge-ology analysis. Then a numerical model was built based on real condition, and the analysis of the stability of the slope under earthquake action was conducted with finite difference program FLAC 3D. Through comparison, the results of numerical simulation verified the correctness of the conclusions of engineering geology analysis, and provided evidence for the design and construction of the hydropower station, also provided ideas for the similar slope seismic stability evaluation.关键词
