| 摘 要： | 以某水电站修复工程坝址左岸1470.00 m高程以下边坡为例,通过地表地质测绘、分析前期勘察成果,研究边坡坡脚崩塌体形成的机制、边坡岩体中结构面组合及对边坡稳定性的影响。利用国际常用的边坡稳定分析软件,对边坡稳定性作出了地质评价,提出了边坡加固措施的地质建议。建议中针对崩塌体部位的处理已完成,实施后效果良好,有效减缓了边坡的再次崩塌风险,对类似工程边坡处理提供了经验参考。

| Abstract: | Taking the slope below E.l.1470.00 m on the left bank of the dam site of a hydropower station as an example,the mechanism of slope foot collapse,the combination of structural planes in the slope rock mass and its influence on slope stability are studied through surface geological mapping and analysis of previous investigation results.The slope stability is evaluated by the slope stability analysis software universally used in the world,and geological suggestions for slope reinforcement measures are proposed.The treatment of the collapsed body in the proposal has been completed,and good results have been achieved after implementation,which effectively alleviates the risk of re-collapse of the slope,and provides experience and reference for slope treatment of similar projects. |
