| 摘 要： | 两河口水电站引水进口边坡主要由砂、板岩组成的陡倾横向坡,最大开挖坡高215 m。本文根据边坡的地质结构及变形破坏特征,分析了边坡的破坏模式及稳定状况。在此基础上,采用三维有限元数值模拟的方法,模拟了工程边坡的分步开挖过程。分析表明,边坡稳定性主要受f34-1等中缓倾角结构面及Ⅴ级岩体的控制,具有沿中缓倾角结构面及Ⅴ级岩体发生滑移破坏的趋势,塑性破坏区主要分布在Ⅴ级岩体及其断层内,水平深度一般为35 m,研究成果对边坡的支护设计具有重要意义。

| Abstract: | The water inlet slope of Linghekou Hydropower station is steep-dip cross fall,which is made up of sandstone and slate.The excavation maximum of slope is 215 m high.The article,based on the geologic structure and the characteristics of deformation-failure of the slope,analyzes the failure mode and steady-state situation of the slope.On that basis,the method of three-dimensional finite element numerical simulation is carried out,which simulates the slope excavation in stages of the engineering slope.The analy... |
