摘要
以重庆某地铁复杂深基坑工程为实例,沿基坑周边布设3类监测项目,在基坑开挖施工过程中,对各监测对象进行了监测。根据监测数据,分别对桩撑、桩锚、板肋支护结构水平和竖向位移、支护桩深层水平位移、基坑周边地表沉降等变形特性进行了综合分析,结果表明,该基坑工程支护设计方案可满足设计和周边环境的要求。
Taking a complicated deep foundation pit of a subway in Chongqing as an example,Three kinds of monitoring items are arranged around the foundation pit,and the monitoring objects are monitored respectively in the process of foundation pit excavation construction.According to the monitoring data,the horizontal and vertical displacement of pile support,pile anchor,plate rib supporting structure,deep horizontal displacement of supporting pile and surface settlement around the foundation pit are comprehensively analyzed.The monitoring results show that the design scheme of the foundation pit engineering support is reasonable,which meets the requirements of the design and the surrounding environment.
