摘　　要：本次研究的水利枢纽工程,其进水口的边坡高度最高达113 m,而边坡的岩体则比较容易风化和软化,因此如何在时常经受地震和水淹浸泡的情况下确保边坡的稳定性是设计时非常重要的问题。通过针对岩石容易风化和软化的特性进行分析和研究可知,在开挖时可立刻采用混凝土素喷的方式来保护岩石,避免岩石较长时间暴露在外,然后再进行挂网喷锚支护来减少边坡的掉块及滑动现象,运行时严格把控水位的消落,以此确保边坡的安全性。In this study,the water conservancy project,the maximum height of the water intake slope is 113m,while the rock mass of the slope is relatively easy to be weathered and softened,so how to ensure the stability of the slope under the condition of frequent earthquake and water immersion is a very important problem in the design.Through the analysis and Research on the characteristics of easy weathering and softening of rock,it is finally required to use the method of plain concrete spraying to protect the rock during excavation,so as to prevent the rock from being exposed for a long time,and then carry out the shotcrete anchor support with hanging net to reduce the drop and sliding phenomenon of the slope,strictly control the water level during operation,and finally ensure the safety of the slope.
