摘　　要：城市的快速发展促使了高层建筑的不断兴建,维护基坑的安全一直是监测工作的重点问题。基坑的深层位移监测又是工程安全防护中的难点,通过监测深层土地的位移变化来判定周围土地的稳定性,对于指导施工具有重大的意义。深层水平位移监测分为滑动式测斜仪和固定式测斜仪,本文以泰安某商业基坑沉降观测为例,介绍了滑动式测斜仪的工作原理及在操作过程中的误差来源,并提出了解决办法。通过工程实例对测斜数据进行分析,在确保施工安全的同时也对类似工程施工提供一些参考。The rapid development of the city promotes the continuous construction of high-rise buildings,and maintaining the safety of foundation pit has always been the key issue of monitoring work.The deep displacement monitoring of foundation pit is also a difficulty in engineering safety protection.It is of great significance to determine the stability of surrounding land by monitoring the displacement change of deep land.The monitoring of deep horizontal displacement can be divided into sliding inclinometer and fixed inclinometer.Taking the settlement observation of a commercial foundation pit in Tai’an as an example,this paper introduces the working principle of the sliding inclinometer and the error sources in the operation process,and puts forward the solutions.This paper analyzes the inclinometer data through an engineering example,which not only ensures the construction safety,but also provides some references for similar engineering construction.
