摘要
在分析北京地面沉降灾害现状、现有监测方法和技术手段基础上,对比InSAR监测与传统分层动态监测、高精度水准测量、GPS测量等在区域地面沉降监测时效性、精确性和经济性等之间的差别,并以北京地铁13号线地面沉降InSAR监测为例,分析其优势与不足,为优化北京地面沉降监测资源、全面开展线性工程地面沉降灾害监测提供参考,以助于推进首都减灾防灾工作进程。
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.
