| 摘 要： | 平洞探坑揭露了锦屏水电站普斯罗沟坝址左坝肩岩体内部存在深卸荷带，该卸荷带生成原因及分布范围将严重影响未来水电站坝肩的稳定及工程处理费用。在充分考虑断层、裂隙带、岩性特点基础上，应用ANSYS软件分析了不同荷载组合情况下普斯罗沟坝址左坝肩高陡边坡岩体深卸荷带的力学特点，建立了解释深卸荷带形成的简单力学模型，确定出深卸荷带应力场异常范围。

| Abstract: | The deep unloaded crack band is located in the high slope of left dam shoulder of Jinping hydopower electrical station; its formation cause and distribution seriously affects the stability and treatment cost. The ANSYS software has been adopted to make analysis of mechanical properties of the high slope by considering the faults and crack band and strata in detail with different loads combination. On the above base a simple mechanical model has been established for the clarification of its formation, the strange stress range is defined. |

| Keywords: | deep unloaded band mechanical model slope |
