摘　　要：通过GPS技术在郑汴新区地面沉降监测项目中的实践和应用,在获取GPS野外观测数据的基础上,进行监测数据处理和对比分析,得出以下结论:①建立了郑汴新区的沉降观测系统,用GPS直接测量的模式成功地进行了5次沉降变形监测;②查明了郑汴新区地面沉降灾害的现状、沉降灾害的趋势及分布规律和地下水为影响地面沉降的主要因素;③通过应用GPS技术对地面沉降进行监测,获得监测点的三维坐标数据,为地质灾害和地质环境综合调查评价及郑汴新区城市建设提供了可靠的基础资料。Through the practice and application of GPS technology in the land subsidence monitoring project of Zhengbian New Area,based on the field observation data,we carried out the monitoring data processing and comparative analysis.The results show that①the subsidence observation system of Zhengbian New Area has been established,and five times of subsidence deformation monitoring have been successfully carried out with the model of GPS direct measurement.②The land subsidence of Zhengbian New Area has been identified.The current situation of disasters,the trend and distribution of subsidence disasters and groundwater are the main factors affecting land subsidence.③By using GPS technology to monitor land subsidence,3D coordinate data of monitoring points are obtained,which can provide reliable basic data for comprehensive investigation and evaluation of geological disasters and geological environment and urban construction in Zhengbian New Area.
