阿坝州双江口水电站左坝肩边坡稳定性分析方法
|
摘要
双江口水电站左岸坝肩边坡部位无区域性断裂通过,由坚硬完整的黑云母钾长花岗岩组成,岩体风化卸荷较浅,通过地质特征分析,结合赤平投影分析和极限平衡法稳定性计算,左岸坝肩自然边坡和工程边坡总体较稳定。仅局部存在小型拉裂岩块和危石,应进行锚固或清除处理。
There isn't any regional fault on the left dam abutment side slope of Shuangjiangkou hydropower station,which is formed by the hard complete biotite kali-feldspar granite weathered lightly.According to geological feature analysis,in combination with stereographic projection analysis and limit equilibrium method stability calculation,the left bank dam abutment natural side slope and engineering side slope are stable in general. There are only the local small tensile break and damage stone block,which must be anchored or removed.
