摘　　要：针对复杂施工环境对基坑水平位移常规监测方法的限制,分析和讨论了固定方位角-自由设站法工作基点的稳定性对监测点的影响,给出相应的修正方法,并结合某深基坑工程实例进行了分析,结果显示该方法能够较为合理地反映基坑水平位移变化情况。In view of the limitation of the complex construction environment on the conventional monitoring method of the horizontal displacement of the foundation pit,this paper analyzes and discusses the influence of the stability of the working base point of the fixed azimuth free station method on the monitoring point,and gives the corresponding correction method.Combined with a deep foundation pit engineering example,the result shows that the method can reasonably reflect the change of the horizontal displacement of the foundation pit.
