基于静态DGPS的堤坝垂向变形监测

摘要

介绍了GPS卫星定位和静态差分GPS(DGPS)技术的工作原理.说明了大地高差与正常高差的关系.通过分析具体工程的沉降监测数据论证了静态差分GPS监测法在堤坝监测中的可行性.%The principle of the GPS and static DGPS were described. The relationship between geodetic height difference and normal height difference were explained. Through analyzing the subsidence deformation monitoring date of real project, static DGPS application in subsidence deformation monitoring of embankment and dam were proved possible.
