以某地铁车站深基坑工程施工为例,介绍了该工程的基本特点、围护结构变形监测方案及测点埋设要求。根据施工特点,将监测数据分为五个工况进行分析,总结了基坑开挖过程中围护结构变形的一般规律,研究表明:在开挖过程中,整个基坑桩体水平位移均在规范规定范围内,基坑较为安全。 Taking the construction of a deep foundation pit of a metro station as an example, the basic characteristics of the project, the deformation monitoring program of retaining structure and the embedding requirements of measuring points are introduced. According to the construction characteristics, the monitoring data is divided into five working conditions for analysis, summarizes the general rules of the deformation of the envelope during excavation process, the study shows that: During the excavation process, the horizontal displacement of the entire pit are Within the scope of the regulation, the foundation pit is safer.
