利用 GPS 建立地面沉降监测基准的研究

摘要

In order to improve large-scope ground subsidence monitoring accuracy,the paper puts forward ground subsidence monitoring datum establishment with continuous GPS monitoring stations. That’s to say,it is to jointly measure common leveling monitoring points and GPS datum point,obtains monitoring network ground subsidence value through data processing model,and lists strict jointly processing formula of datum sub-sidence and leveling detection data. Through analyzing new Tianjin coastal region,it proves the method rational.%为了提高大范围地面沉降监测精度，提出一种利用GPS连续监测站建立地面沉降监测基准的方法，即将普通水准监测点和GPS基准点连测，并通过数据处理模型得到监测网的地面沉降值，列出了基准点沉降量和水准网观测数据联合处理的严密公式，通过分析天津滨海新区的实例，证明了该方法的合理性。
