| 中文摘要:本文根据多年来的垂直形变资料，系统而深入地研究地面垂直形变的演化特征及其规律，并结合地下水活动和地面沉降分层标的监测资料，分析地面沉降成因。西安地区由于过量开采地下水，引起地面急剧沉降。 |

| Abstract:Based on multi-period observation data of vertical deformation, the authors have systematically analyzed and thoroughly studied the evolutionary characteristics and stratification criteria of ground vertical deformation in Xi an. The reason for the ground subsidence is also analyzed by integrating the observation data of groundwater activity and slice indicators of ground subsidence. The main reason for the ground subsidence is the excessive exploitation of underground water. |
