Abstract:
In order to accurately monitor and effectively manage the ground subsidence in Taiyuan city of Shanxi province,China, PS-DInSAR method was adopted to monitor the ground surface subsidence based on the 20 scenes Sentinel-1A image between February 17, 2016 and February 18, 2018. The monitoring results showed that the main subsidence areas in Taiyuan city were located in Xiaodian, Wujiabao, Beigunian, Yangjiayu and Xizhang. And the most serious ground settlement occurred in the Xiaodian. During the past two years, the ground subsidence rate in Taiyuan city firstly increased and then decreased.Tianzhuang fault had played a significant role in the ground subsidence rule in Xiaodian. Compared with previous studies and wells in Taiyuan city, the results of ground subsidence in Taiyuan city based on PS-DInSAR method could meet the monitoring and management needs.
