摘　　要：针对施工场地狭小 ,无法建立稳定测站的情况 ,提出在移动点上通过观测角度变化 ,间接计算出该点水平位移的方法 ,进一步分析了计算过程中的误差传递 ,确定了观测精度 。The construction site is usually quite narrow. It is very difficult to find a stable station for survey. A solution is put forward. First, choose some key points as stations; then survey the changes of certain angles; finally the changes of angles are converted into horizontal displacements. For the more, the error transmission process in calculation is analyzed. Some advice is given for the selection of devices.
