摘要
利用GPS进行地面沉降监测能够解决传统测量方法工作量大、周期长的问题。该文结合实例,论述了GPS在地面沉降监测中的应用,分析了GPS测量方法的优点和误差,提出了GPS测量地面沉降的适用条件。
GPS is beneficial to solve the problem,which takes long time and lots of work to monitor land subsidence area by traditional methods.Combining with the example,this paper discusses the application of GPS to monitoring land subsidence area, analyses the advantages and errors of methods of GPS survey, and puts forth the suitable conditions of monitoring land subsidence area by GPS.
