摘要
基于在变形监测中全站仪的使用,利用全站仪能同时观测角度、距离和高程的特点,针对施工场地狭窄,无法运用传统方法进行变形监测的情况下,对深基坑的变形监测提出了三维坐标法。通过观测变形点的坐标变化,计算出变形监测点的水平位移和沉降量。
By using total station to survey the angle,distance and elevation at the same time,the differences of coordinate of observation points can be measured,and the horizontal displacements and differential settlement can he attained.h is proposed that the 3 D coordinate method should be used as the solution by narrower construction sites where the traditional methods are not applicable. According to the analysis of the precision and the comparison of the data of settlement measurement ,the precision of this method meets the requirement of the observation of deformation.
