某深基坑突涌事故应急处理与分析

Emergency Treatment and Analysis of a Deep Foundation Pit Surge Accident

地下水治理为基坑设计和施工的关键环节,其也多为基坑遭遇险情的重大诱因,很多基坑事故都与地下水相关。地下水处理不当或险情发生后处理不及时都极易引发基坑事故,故在基坑支护设计及施工中对地下水处理是否得当尤为关键,否则或会带来灾难性的后果。文中通过详细介绍某项目基坑突涌应急抢险及后续处理过程,对相关经验教训进行总结,并对类似工程的防范、应急、及处理措施给出一些建议。

Groundwater treatment is a key link in the design and construction of foundation pit,and it is also a major inducement for foundation pit to encounter danger.Many foundation pit accidents are related to groundwater.Improper ground water treatment or untimely post-treatment of dangerous situations are very easy to cause foundation pit accidents,so it is particularly important to treat ground water properly in the design and construction of foundation pit support,otherwise it may bring disastrous consequences.In this paper,through the detailed introduction of the emergency rescue and follow-up treatment process of the foundation pit surge of a project,the relevant experience and lessons are summarized,and some suggestions on the prevention,emergency and treatment measures of similar projects are given.
