摘　　要：水平位移监测的首要工作是建立基准(设置基准点和工作基点),基本要求是在整个变形监测期间保持点位稳定可靠、使用方便;本文介绍的后方交会法即是一种建立基准的方法,在基坑周边场地狭窄、基坑自身形状不规则、监测精度要求高的条件下,实施本方法获得了较好的效果。The primary work of horizontal displacement monitoring is to establish benchmark （set the reference point and working point）, the basic requirement is to keep the point stable and reliable, and easy to use,during the whole deformation monitoring ; Resection method in this paper is a kind of method to establish the benchmark. In the condition of narrow field around the foundation pit whose shape is irregular, in high-accuracy surveying, the implementation of the methods obtain good results.
