| 摘 要： | 水能资源富集的西部地区,深切河谷高陡岸坡稳定性问题严重制约了水电建设项目的顺利进行。锦屏一级水电站的高陡边坡稳定性问题十分突出,其左岸1#危岩体边坡即为典型案例之一。1#危岩体边坡为缆机平台边坡,其稳定与否直接关系到缆机平台的顺利开挖。本文运用GEO-Slope方法对其进行了稳定性研究,结果表明,其潜在失稳范围的后缘边界为黄斑岩脉X,底边界为f_(LL2)断层。开挖后该范围块体基本处于极限平衡状态,再加上施工扰动,基本不能自稳,因此建议在开挖前采取相应的支护措施。

| Abstract: | The stability of high steep slope severely restricts the hydropower projects to construct smoothly in the west China with rich hydropower.The problem of stability of Jingping First Stage Hydropower Station is prominent, and the No.1 rock mass slope at the left bank is one of typical cases of stability problem.The No.1 rock mass slope is the cable crane platform slope whose stability direcdy relates to that whether the cable crane platform can be excavated successfully.This paper applies the GEO-Slope to res... |
