摘　　要：为解决高水头软弱富水地层中,悬挂式基坑深层旋喷桩水平封底失效前后出现的问题,对预防和解决方案进行了分析。针对分析得出的结果,研发出了相应的解决基坑突涌的方法。采用该方法能预防和解决水平封底缺陷带来的基底突涌风险,可供类似项目借鉴。In order to solve the problems before and after the horizontal bottom sealing failure of deep rotary jet grouting pile in suspended foundation pit in high head soft water rich stratum, the prevention and solution are analyzed. According to the analysis results, the corresponding method to solve the foundation pit inrush is developed. This method can prevent and solve the risk of base inrush caused by horizontal bottom sealing defects, which can be used as a reference for similar projects.
