浅析深基坑开挖风险识别及塌方应急处理

Analysis of the Risk Identification and Emergency Treatment of Deep Foundation Pit Collapse Excavation

深基坑开挖施工环境复杂,容易发生基坑塌方群死群伤的安全生产事故。本文通过对某工程支护结构在地下室施工过程中发生局部塌方事件进行分析,阐述及对其进行处理的施工实践体会,希望能够给类似项目工程管理人员在深基坑土方开挖过程中做好风险识别及塌方应急处理工作提供一些帮助。

Deep excavation construction environment is complex, and it is prone to foundation pit collapse and safety acident. Based on the analysis of local collapse events of an engineering supporting structure in the basement construction process, elaborates the construction practice experience and its treatment, hoping to provide some help to the similar project management personnel to do a good job in the risk recognition and emergency treatment of collapse in the excavation of deep foundation pit earthwork.
