摘要
在广泛分析目前深基坑降水的设计计算理论和施工的基础上,建立了三维渗流的有限元模型,编制了三维有限元计算程序,并以武汉长江隧道武昌盾构井深基坑降水工程为例进行计算。通过将有无悬挂式帷幕两种工况的水头降深计算结果与实际存在悬挂式止水帷幕的实际监测值进行对比,定量说明悬挂式止水帷幕对基坑降水的影响。
Based on an extensive analysis to the design theory and construction of the dewatering of deep foundation pit excavation. The 3-dimensional finite element seepage model is established and the 3-dimensional finite element program is accomplished. Dewatering engineering of the deep foundation pit of the shield well in the project of the Changjiang River tunnel in Wuhan is taken as an example to calculate. Through comparing the calculate results with the measured data of the water level in the following two status that have pensile curtain or without, to illustrate quanitvely the infection of pensile curtain to seepage on foundation pit dewatering.
