摘要
文中以实际工程为案例,对基坑情况进行了介绍,并根据施工步骤对施工过程的稳定性进行了评价计算,得到开挖过程中基坑边坡的安全系数最小为1.251,满足规范要求,并针对其工程特点提出关键技术建议,最后通过开挖过程中基坑侧壁监测数据进一步论证了该开挖方式的安全性,以供参考.
Abstract
In order to further improve the quality of hydraulic pump station foundation pit engineering,this article takes actual engineering ca-ses as the research object,introduces the situation of the foundation pit,evaluates and calculates the stability of the construction process based on the construction steps,The minimum safety factor of the foundation pit slope during excavation is calculated to be 1.251,which meets the requirements of the specification.and puts forward key technical suggestions based on its engineering characteristics.Finally,the safety of the excavation method is further demonstrated by the monitoring data of the side wall of the foundation pit during the excavation process.This has certain reference significance for the subsequent development of related projects.
