摘要
采用三维渗流场与应力场耦合有限元程序,计算了南京长江隧道梅子州工作井基坑工程降水对周围环境的影响规律,在此基础上提出了采用坑外止水帷幕的方法来减少降水的影响,并对超深帷幕的相关参数和施工工艺进行了介绍。
Taking the finite element program of seepage field coupled with stress field, it calculates the influence law of foundation pit engineering dewatering of Meizizhou working shaft working well of Nanjing Changjiang river tunnel to its surrounding environment, on the basis of which, it puts forward that applying waterproof curtain out of pit to decrease the influence caused by dewatering, and introduces relative parameters and construction technique of super-deep curtain.
