摘要
介绍了天津某深基坑工程开挖实例及施工过程的监测情况。通过对开挖过程中的坑周土体水平位移、支护结构顶部水平位移、立柱沉降以及周围管线等的现场施工监测数据的分析,探讨了深基坑开挖过程对周围环境的影响,为考虑施工因素的深基坑设计提供了依据,为今后类似工程的设计施工积累了经验。
In this paper,a case study on excavation of deep foundation pit in Tianjin is proposed.A test section was established in construction site.Some elements such as bracing responses,lateral displacement of soils,column settlement and displacement of pipelines were investigated.Based on construction monitoring,data about environmental effect are obtained.This paper analyzes these data and also discusses in detail the characteristics of the influence on surroundings during excavation.The findings show that the design of the bracing structure is feasible and meets the requirements of environment.It also provides a practical reference for the design and construction of similar projects.
