乌江沙沱水电站边坡稳定性分析

ccording to outsourcing technical requirements of anti-seismic calculation on Shatuo hydropower station, in the project, stress, displacement and stability are calculated on retaining section, plant water section, shiplift section and hub area slope. Based on static and dynamic FEM analysis, the result of the stability analysis was got, which was one of the typical slope of approach channel. Firstly, strength reduction method was used to make static calculation to find out the plastic zone. So the slide plane was got correspondingly. Then dynamic FEM analysis was made with viscous-spring boundary conditions. Dynamic safety coefficients can be got under three seismic waves. The results turned out that Shatuo slope was safe and the global stability was guaranteed.
