摘要
本文综合运用地形、地质构造等基础信息,建立西昌地区的数值模型,定量分析由荷载引起的点位沉降变化等干扰对跨断层形变测量的影响。采用FLAC^3D软件对包含西昌跨断层场地及附近尾矿库的数值模型进行计算,结果表明,尾矿库矿渣堆积不是引起西昌场地水准观测资料出现异常的原因。
We establish a numerical model for the research area using basic information such as terrain,geological structure,etc.Then,we calculate and analyze the observation point’s subsidence,which is caused by the change of the load weight.We calculate the numerical model,which includes the across-fault site Xichang and the tailings nearby,using FLAC 3D software.The results show that the tailings accumulation is not the cause of the unusual change of the level observation data in the across-fault site Xichang.
