临泉县某综合管廊基坑施工监测方案设计研究及应用

Design and Research on Construction Monitoring Project for Foundation Pit of Integrated Pipe Gallery in Linquan County

在地下工程中,基坑工程是其最重要的基础,为保障工程安全进行,在基坑开挖的同时,还需要对基坑施工过程进行监测。本文结合临泉庐阳现代产业园庐阳大道综合管廊深基坑工程,针对工程采用钢板桩加钢支撑的支护形式,以基坑围护结构的累积变形量大小作为参考手段的监测方法,对施工过程中基坑的变形、地下水、坡顶位移等指标进行科学监测,总结和分析了监测结果,研究成果为其他管廊的设计,施工和监测提供借鉴和参考。

In underground engineering,the most important section is pit engineering.In order to ensure the safety of the project,excavation of foundation pits requires monitoring of the construction process of foundation pits.In this article,according to scientific monitoring of the deep foundation pit of Luyang Avenue,Luyang Modern Industrial Park,which uses the supporting form of steel sheet pile and steel bracing,the cumulative deformation of the foundation pit retaining structure is used to be the monitoring method of the foundation pit,groundwater,and the top of the slope during the construction process,relative results will be provided for design,construction and monitoring of other tubes.
