基于时序InSAR技术的上海城区地表沉降监测及风险分析

Surface Settlement Monitoring and Risk Analysis in Shanghai Based on Time Series InSAR Technology

开展地面沉降研究的目的在于预防、控制并减缓地面沉降的发生和发展。本研究采用pearson相关分析方法对由2种时序InSAR技术处理得到的监测结果进行交叉验证,以保证监测结果的准确性。并结合各种指标和形变监测结果进行地表沉降风险性评估,发现研究区内存在多个不均匀分布的沉降漏斗,且位于较高风险区和高风险区。

The purpose of surface settlement research is to prevent,control and slow down the occurrence and development of surface settlement.In this study,pearson-related analysis methods were used to cross-verify the monitoring results obtained by the two time series InSAR techniques to ensure the accuracy of the monitoring results.Combined with various indicators and deformation monitoring results,the risk assessment of surface settlement was carried out,and it was found that there were multiple unevenly distributed sedi-mentation funnels in the study area,and they were located in higher risk areas and high risk areas.
