摘　　要：为研究不同降雨和施工条件下岩质边坡的稳定性问题,以某水库左岸开挖岩质边坡为研究对象,在充分分析其工程地质条件和边坡岩体物理力学参数的基础上,对其失稳模式进行初步判别,然后从二维和三维角度分别分析了该边坡在暴雨期、施工开挖和施工加固后的应力应变状态和稳定性,并提出了针对性的加固处理措施。In order to study the stability of rock slopes under different rainfall and construction conditions,the excavation of a rock slope on the left bank of a reservoir is taken as the research object,and the basis of full analysis of its engineering geological conditions and slope physical and mechanical parameters On the basis of preliminary identification of its instability model,the stress and strain state and stability of the slope during heavy rain,construction excavation and construction reinforcement were analyzed from two-dimensional and three-dimensional angles respectively,and targeted reinforcement was proposed Treatment measures.
