固定式测斜仪在地铁车站基坑监测中的应用

针对人工监测频率较低、外部环境影响大等问题，依托某地铁车站基坑施工，采用固定式测斜仪来获取地铁车站基坑墙体深层水平位移，辅以人工监测定期校核的方式，获取不同施工阶段位移变形情况。结果表明：在考虑监测成本及现场实施的条件下，基坑施工监测中采用间距不等相结合的固定式测斜仪，能够更贴切地反映地铁车站墙体变形情况，且具有较滑动式测斜仪效率高、数据贴合度高等优势。

Application of Fixed Inclinometer in Foundation Pit Monitoring of Metro Station

Aiming at the problems of low frequency of manual monitoring and great impact on the external environment, based on a subway station foundation pit construction, the fixed inclinometer is used to obtain the deep horizontal displacement of the foundation pit wall of the subway station, supplemented by manual monitoring and regular verification to obtain the displacement and deformation in different construction stages. The results show that under the conditions of considering the monitoring cost and on-site implementation, the fixed inclinometer combined with unequal spacing used in the foundation pit construction monitoring can more accurately reflect the wall deformation of the subway station, and has the advantages of higher efficiency and higher data fit than the sliding inclinometer.
