西部某库区高边坡稳定性研究

Stability Analysis of a High Slope in Reservoir Area in West of China

以西部地区某水库库岸危险边坡为例,运用Geo-studio系列软件模拟水库蓄水、地震对该危险边坡影响,通过有限元法计算分析该边坡稳定性及坡体应力应变大小,核算出该边坡在水库正常蓄水后为危险边坡。利用软件模拟坡脚加固措施后,对边坡重新进行核算得出,加固后该边坡符合稳定性设计要求。

Taking a dangerous slope in reservoir area in west of China as the example, using the Geo-studio software to simulate reservoirs, seismic impact on the dangerous slope, this paper analyzes the stability and stress on the slope by finite element method. It gets the results that the slope is in dangerous after ordinary water storage. By using the software to simulate reinforcement measures on slope ends, the author analyzes and calculates the slope again,and gets the conclusion that this slope can meet the stability design require- ments after reinforcement.
