摘　　要：针对当前水平位移监测缺乏精度分析的现状,提出了全站仪小角监测的精度分析方法,有效评价了水平位移精度。利用恒天国际大厦基坑水平位移观测数据,对水平位移进行定性定量与可视化分析,对不稳定点进行累计位移量分析与稳定性分析,并评估水平位移监测所达到的精度等级。In view of the lack of precision analysis in the current horizontal displacement monitoring, the precision analysis method of small angle monitoring with total station is put forward, and the precision of horizontal displacement is effectively evaluated. Based on the horizontal displacement observation data of foundation excavation of Hengtian International Building, the horizontal displacement is analyzed qualitatively and visually, the cumulative displacement and stability of unstable points are analyzed, and the precision level of horizontal displacement monitoring is evaluated.
