地形变观测结果表明,葛州坝水库西南部邻近的断层与破碎帝在水库蓄水后都发生了不同程度的地形变。本文根据实测资料,计算分析了区域应变场与应变误差,探讨了断层区域的变形机制,指出断层上的形变与坝库区域的地形变有着良好的对应关系,水库蓄水使邻近断层上的应力状态有所改变,断层上的形变是坝库近区形变在邻近构造边界上的响应。 The results of the deformation observation show that the faults and broken imperial tombs near the southwestern part of Gezhouba Reservoir have varying degrees of deformation after the impoundment in the reservoir. Based on the measured data, the field strain field and strain errors are calculated and analyzed, and the deformation mechanism of the fault area is discussed. It is pointed out that the deformation on the fault has a good correspondence with the deformation of the dam area, and the reservoir impoundment makes the stress on the adjacent fault The state has changed, and the deformation on the fault is the response of the near dam deformation in the adjacent structural boundary.
