摘要

针对土压平衡式盾构机在高水头强透水地层掘进工程中，排土器出口易出现地下水渗出的现象进行了理论研究。通过建立地下水在盾构机内的渗流计算模型，提出了判别地下水渗出发生与否及其出渗量大小的方法，阐明了盾构施工中发生地下水出渗的机理。利用这一模型计算了出渗发生时地下水流失情况，对影响出渗发生的各相关参数进行了分析，为施工中克服和避免这一现象提供了理论依据。

Abstract

When earth-pressure balance (EPB) shield is used in high permeability ground as well as high groundwater pressure

groundwater will flows through screw conveyor (Flowwing)

this will lead the loss of great quantity of groundwater and even the halt of excavation. Based on the steady-flow seepage theory and shield driving principle

a method for judge Flowing is provided

and a model for study the seepage of groundwater in chamber and screw conveyor is built to explain the mechanism of Flowing. With the model

the parameters such as soil condition

shield geometry

excavation instruction which relate with Flowing are analyzed and the results give some useful conclusions and suggestions to predict and avoid flowing. The model can also be used to calculate the discharge of groundwater.
