摘　　要：采用SBAS-InSAR技术获取WLL水库及周边区域地表沉降信息。结果表明:1)WLL水库大坝表现为整体下沉,沉降速率在逐年减小后趋于稳定;2)受水库水位、大坝自重及地下水位等因素的共同影响,大坝沉降速率、累积沉降量表现为东南至西北方向逐渐增大;3)水库周边区域沉降未对大坝产生实质性影响。We obtain by SBAS-InSAR technique the surface subsidence information of WLL reservoir and its surrounding area.The results show that:1)The settlement of WLL reservoir dam is overall,the settlement rate decreases year by year,and the settlement tends to be stable.2)Due to the influence of reservoir water level,dam weight and underground water level,the settlement rate and cumulative settlement of the dam gradually increase from southeast to northwest.3)The subsidence around the reservoir has no substantial influence on the dam.
