| 摘 要： | 1引言长江中下游沿岸大都位于长江一级阶地之上,地基土呈典型的二元结构。上部由透水性弱、强度低的粘性土层组成;下部由强度高、透水性强的砂、砾、卵石层组成,富水性好,在两层结构之间,间或出现厚度不一的粉砂过渡层,抗渗强度低1,2]。这样更增加了地下工程支护与施工的难度,

| Abstract: | 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. |
