摘要
针对沉降监测中普通水准观测方法无法实施的问题,本文通过对三角高程测量原理与误差来源的分析,研究了中间设站式三角高程测量实施沉降监测的方法,分析了观测精度及可行性。实验表明,该方法可以方便快捷地获取待监测体的沉降数据,提高了工作效率,测量精度达到了建筑变形测量等级二级精度要求。
Aiming at the problem that the ordinary leveling observation methods could not be implemented in subsidence monitoring, through the triangulation measurement principle and the analysis of error sources, the method of the implementation of the intermediate station-type precise trigonometric leveling in subsidence monitoring was studied in this paper, observational accuracy and feasibility were also analyzed. The experiments showed that this method could gain the subsidence data of the monitoring body more quickly and easily, meantime the efficiency of working could be raised, moreover, it could have the guiding significance and practical value in the subsidence monitoring in the complicated environment.
