摘要
为研究西部地区岩质边坡的稳定性,以青海浪加水库库区的一个库岸为例,运用二维刚体极限平衡分析方法对库岸边坡进行稳定性分析,并分析水位平均变化速率对岸坡稳定的响应,以及进行平面滑动岩坡稳定性分析,评价结果较为客观地反映了工程实际情况,对该类地区岩质边坡稳定性进行分析预测具有一定的指导意义和参考实用价值.
In order to study the stability of rock slopes in the western region, this paper uses two--dimension- al limit equilibrium method to analyze the stability of a bank slope in Qinghai Langjia reservoir area, as an ex- ample. What＇s more, the responses of the average rate of water--level changes to the bank stability are ana- lyzed, as well as the stability of the plane sliding rock slopes. The analysis results reflect the engineering practice objectively. To analyze and predict the stability of rock slope in this region have certain guiding sig- nificance and reference practical value.
