摘　　要：深层水平位移监测是深基坑动态化监测中不可缺少的监测环节,该方法以其特有的深层土体位移敏感性、前瞻性,在深厚软土地区、滨海地区等具有较大安全风险的深基坑工程中应用较广,是一种准确了解深层土体水平位移情况的方式,为动态化施工、信息化施工提供了依据。论文对深层水平位移测量原理进行了研究,并结合广东省珠海市横琴粤澳深度合作区的深基坑工程项目分析了深层水平位移测量与全站仪测量结果不一致的原因,指出了测量误差的存在,并提出了减小误差累积的测量方法。Deep horizontal displacement monitoring is an indispensable monitoring link in the dynamic monitoring of deep foundation pits.With its unique deep soil displacement sensitivity and forward-looking,this method can be used in deep soft soil areas,coastal areas and other deep areas with greater safety risks.It is widely used in foundation pit engineering.It is a way to accurately understand the horizontal displacement of deep soil,and provides a basis for dynamic construction and information construction.In this paper,the principle of deep horizontal displacement measurement is studied.This paper analyzes the reasons for the inconsistency between the deep horizontal displacement measurement and the total station measurement results based on the deep foundation pit engineering project in the Hengqin Guangdong-Macao Deep Cooperation Zone in Zhuhai City,Guangdong Province.The article points out the existence of measurement errors and proposes a measurement method to reduce the accumulation of errors.
