Abstract:

There are a few researches on predicting subsurface ground movements induced by shield tunneling via brief estimating method till now. Based on the method used to calculate ground elastic displacement around deep tunnel and some researches on gap parameter of shield tunnel, a brief method for estimating subsurface ground horizontal movement induced by shield tunneling is presented. And a new method is presented to describe the profile of ground settlement around a shield tunnel. And then it is used to estimate subsurface ground settlement with the equation presented by Mair. And the feasibilities of these proposed methods for estimating subsurface ground movements induced by shield tunneling are verified via contrasting their analysis results with finite element analysis results and measured data of some typical project cases.

Key words: shield tunneling, subsurface ground, movement
