复杂环境下基坑群施工的安全风险控制技术

Security Risk Control Technology for Foundation Excavation Construction in Complicated Environment

根据城市内部发展建设的实际需求,提出了在复杂环境下深基坑开挖的安全风险控制技术。结合工程实例介绍了基坑开挖、支护及监测方案。各类施工监测数据表明基坑分区分层开挖、施工穿插进行以及五轴施工的科学使用可有效控制施工风险,减小对周边环境的影响,缩短施工日期,在城市建设中带来巨大的社会及经济效益。

According to the actual demand of urban internal development and construction,the safety risk control technology of deep foundation excavation in complex environment is put forward. Combined with engineering examples,the excavation,support and monitoring program of foundation excavation are introduced. Various types of construction monitoring data show that the stratified excavation of foundation excavation partitions,the crossed construction and the scientific use of five-axis construction can effectively control the construction risk,reduce the impact on the surrounding environment and shorten the construction date.Bringing huge social and economic benefits in the city construction.
