| 摘 要： | 拟建的某水电站工程位于亚曼苏活动断裂的下盘,为了了解亚曼苏断裂强变形带宽度的范围,确定断裂的避让宽度,为水电站工程选址提供参考依据,利用地表强形变带宽度测量、大型探槽开挖揭露和高密度电法探测的方法,对断裂的强变形带宽度问题进行了详细的分析研究。结果表明,该断裂下盘的强变形带宽度小于50 m,小于相关规范中100 m的避让距离,建议该水电站工程重要构筑物的避让距离为100 m。 |
| 关 键 词： | 活动断裂 强变形带 避让距离 |

| Abstract: | The proposed hydropower project is located in the footwall of the Yamansu active fault. In order to understand the width of the surface deformation of the Yamansu active fault, and determine the safety distance of avoidance, multiform detection methods were abopted. The surface strong deformation width measurement, large trenching exposed and high density electric method indicate that the deformation width of the fault footwall is no more than 50 m. The results of the strong deformation width of the fault footwall is less than the avoidance distance related specifications. It is recommended that the avoidance of the hydropower project structures distance of 100 m. |
