摘　　要：针对某紧邻汉江及长江的超深基坑项目的高水压涌水现象,提出了采用直埋钢护筒、大功率水泵抽排、涌水量监测的处理技术。实践表明,直埋钢护筒能有效控制涌水对基坑施工的影响范围,大功率水泵抽排实现了涌水外排的能力,保证了基坑工程的正常施工,涌水量监测可以有效地预测基坑的安全性。相关结论可供类似项目参考。For the phenomenon of high water pressure surge water of a super-deep foundation pit project adjacent to the Han River and the Changjiang River,the use of directly buried steel casing,high-power pump pumping,surge water monitoring processing technology is proposed.Practice shows that directly buried steel casing can effectively control the scope of influence of water surges on the pit construction,high-powered pump pumping to achieve the ability to discharge water surges,to ensure the normal construction of the pit project,and water surges can be effectively monitored to predict the safety of the pit.The relevant conclusions can be used as references for similar projects.
