基坑开挖过程中对周边地表沉降的影响分析















摘要：随着城市建设的发展，高层建筑物越来越多。在城市高层建筑建设过程中，开挖基坑问题凸显，基坑工程施工越来越多，开挖深度越来越深，开挖面积越来越大，使用周期也是比以前越来越长。由于基坑周围及地下环境错综复杂。为实现基础设施施工顺利进行，需要对施工过程中各类要素、各个环节进行必要的监测和控制，为施工单位提供及时有效的监测数据，配合施工队伍监测工作，共同维护现场的安全。本文通过对石景山衙门口基坑开挖过程中地表沉降的监测分析，探讨了基坑监测过程中地表沉降的影响及其规律。

Analysis on influence of foundation pit excavation on surrounding ground settlement
Abstract：Abstract: with the development of urban construction, there are more and more high-rise buildings. In the process of high-rise building construction in the city, the problem of foundation pit excavation is prominent. There are more and more foundation pit engineering construction, deeper and deeper excavation depth, larger and larger excavation area, and longer service life than before. Due to the complex surrounding and underground environment of foundation pit. In order to realize the smooth progress of infrastructure construction, it is necessary to monitor and control various elements and links in the construction process, provide timely and effective monitoring data for the construction unit, cooperate with the monitoring work of the construction team, and jointly maintain the safety of the site. Based on the monitoring and analysis of the ground settlement in the excavation process of Yamen foundation pit in Shijingshan, this paper discusses the infl
