| Abstract: | Based on the analysis of problems associated with land subsidence and the existing monitoring methods and technical capabilities in Beijing, this paper compares the differences in timeliness, precision, and economy of regional land subsidence monitonng among InSAR monitonng, traditional hierarchical dynamic monitoring, high-precision leveling, and GPS measurements. Using the case of land subsidence monitonng in the line 13 subway in Beijing, the advantages and disadvantages of each approach were analyzed, and advice presented for optimizing land subsidence monitonng resources and implementing linear engineenng land subsidence disaster monitonng, which will help to promote the progress of disaster prevention and reduction in Beijing. |
