| 摘 要： | 地面沉降是西安市最为严重的地质灾害之一。本文基于SBAS-InSAR技术处理了西安市2018—2021年36景Sentinel-1A影像，获取了西安市最新的地表形变特征，并分析其成因。研究表明：(1)2018—2021年西安市主要地表形变区域为鱼化寨地区、电子城地区、三爻-凤栖原地区、城墙南部区域；(2)鱼化寨及电子城地区已转为抬升趋势，城墙南部一直处于抬升阶段，三爻-凤栖原地区呈下沉趋势；(3)西安市地表形变主要受承压水开采及回灌的影响，地裂缝则显著影响了地表形变的分布及走向，建筑载荷也对地表形变有一定的影响。

| Abstract: | Land subsidence is one of the most serious geological disasters in Xi'an city.In this paper, 36 Sentinel-1A images of Xi'an city from 2018 to 2021 are processed based on SBAS-InSAR technology to obtain the latest surface deformation characteristics of Xi'an city and analyze its causes.The results show that:① the main surface deformation areas in xi'an city from 2018 to 2021 are Yuhuazhai area, electronic city area, Sanyao-Fengqiyuan area and southern part of city wall area. ② The Yuhuazhai and Yuecheng areas have been uplifted, while the southern part of the city wall has been uplifted, and the Sanyao-Fengqiyuan area still shows a downward trend. ③ The surface deformation of Xi'an city is mainly affected by confined water mining and recharge, and the distribution and trend of surface deformation are significantly affected by ground cracks, and the building load also has a certain influence on the surface deformation. |
