摘要
北京市地面沉降监测系统由地面沉降监测网、地面沉降专门监测网、GPS监测网、地下水位动态监测网及InSAR监测网构成.结合北京市近年来地面沉降监测工作,分析总结了标孔监测和质量控制方法,提出了将GPS监测分为控制网和监测网两级监测的方法,提高了监测精度,尝试采用InSAR测方法对部分重要轨道交通进行地面沉降专项监测研究.对地面沉降监测网络建设及优化有一定的指导意义.
The Beijing Land Subsidence Monitoring System consists of land subsidence monitoring network, leveling monitoring network, GPS monitoring network, groundwater dynamic monitoring network and InSAR monitoring network. Based on the information accumulated through the land subsidence monitoring work of Beijing City in recent years, this article analyses and summarizes the bedrock bench mark and layered bench mark monitoring and quality control method. The two-level monitoring method, i.e. GPS monitoring control network and monitoring network, improves the monitoring accuracy. The InSAR method is adopted to initiate the land subsidence special monitoring research on some important rail traffic. The article also gives some guidance for land subsidence monitoring network construction and optimization.
