摘要
深基坑突水一直是工程施工中的重大安全隐患,如何准确判断突水原因、突水来源是解决及控制突水灾害的关键。本文以深圳地铁5号、9号线换乘站深基坑突水事件为背景,从地层条件、周边环境探讨了基坑突水成因,提出在人工湖影响下基坑突水应急处理措施,通过突水源头治理、突水通道截断、突水位置堵漏三步处理工序,有效控制及避免突水情况的进一步恶化。
Water inrush in deep foundation pit has always been a major safety hazard in engineering construction. How to accurately determine the causes of water inrush and the source of water inrush is the key to the solution and control of water inrush. In the background of the water inrush event in the foundation pit of the transfer station of line 5 and 9 of Shenzhen metro,the causes of water inrush from perspective of the stratum condition and the surrounding environment were discussed,and the emergency treatment measures for water inrush in foundation pit under the influence of artificial lake were put forward. Through three-step processing procedure including the water inrush source control,the water inrush channel truncation and the water inrush position plugging,further deterioration of water inrush condition was effectively controlled and avoided
