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 ,提出了选择相应仪器的标准
Aiming at the situation that the construction site is small and the stable stations can not be established, a method of indirectly calculating the horizontal displacement at the moving point by observing the angle is proposed. The error propagation in the calculation process is further analyzed and the observation accuracy is determined. Select the appropriate instrument standard
