针对在工程勘测过程中遇到山谷沟壑、森林茂密,或有建筑物遮挡等特殊环境所引起的测量质量不稳定、定位精度低甚至无法进行观测等情况,本文基于GPS和BDS这两种主要测量技术,构建了一套高精度的变形监测系统.经实测数据的处理分析,表明本组合变形监测系统的定位精度高,稳定性好,能够改善GPS变形监测系统观测不准的现象,在勘测设计及工程施工等方面有较强的适用性,具有广阔的应用前景.%Proposed for some problems such as unstable measurement qualities,low positioning accuracy,even cannot observe those are caused by the special environment of the valley,the dense forest,or the building block in the process of engineering survey.In this paper,based on GPS and BDS two kinds of main measurement technology,a set of high precision deformation monitoring system is constructed.Moreover,the analysis of the measured data shows that the combined deformation monitoring system has high positioning accuracy and good stability.It can improve the observation of GPS deformation monitoring system.It has a strong applicability in the survey and design and engineering construction.
