| 摘 要： | 某高边坡工程开挖垂直高度达62 m，区域地质条件复杂，边坡表层卸荷深度大，多为碎裂状结构岩体，边坡开挖受断层控制，边坡顶部又有输电塔，对位移控制要求较高。以该边坡为研究对象，运用工程地质、岩体力学、数值模拟等理论和方法，研究了边坡的稳定性，提出了确保开挖安全和边坡长期稳定的支护措施。

| Abstract: | The high slope is to be excavated up to 62 m high vertically with complex regional geological condition, large unloading depth over the slope surface and predominant in fractured rock mass ; thus the slope excavation is controlled by faultage with transmission tower at the top requiring displacement limit strictly. Taking Mawo Slope as the objective, the slope stability is studied by use of engineering geology, rock mass mechanics, and numerical simulation, and then the support measures ensuring excavation safety and long-term stability are proposed. |
