Monitoring and analysis of surface subsidence of Qingdao West Coast New Area subway using time-series InSAR
This article applies time-series InSAR technology to obtain the settlement rate field and cumulative settlement amount field of Qingdao West Coast New Area from April 2017 to June 2022,and selects three subway lines with characteristic areas and different spatial spans for specific settlement analysis.The experimental results show that the subway line is in a stable state overall,with regional uneven settlement problems in the sections from Gangshan Road,Jialingjiangxi Road Station to Xiangjiang Road,and Xinghaitan Station to Lingshanwan Station.Some lines have a relatively high settlement rate.The spatiotemporal evolution map along the subway line in the West Coast New Area can accurately reflect the settlement situation of the subway line in the area,providing a reliable analytical basis and data support for subway settlement monitoring and geological disaster prevention in the West Coast New Area.
