Abstract

Abstract

Peck method and Stochastic Medium Model(SMM) were widely used for predicting ground movement induced by shield tunneling in China.But it is difficult to determine the parameters of this two methods.So the relation between tunnel relative depth and maximum surface settlement was plotted according to 46 measured engineering cases.It shows that ground settlements induced by shield tunneling change greatly when tunnel relative depths are less than 5;influence of tunnel relative depth is little when it is greater than 5.Based on the maximum surface settlement calculating formula of soil non-uniform convergence model,and according to Peck and SMM method,an applied calculation method was deduced,which considered the influence of all different soil conditions,tunnel radius and depth,whose rationality was validated by the analysis of 5 engineering cases.
- shield construction,
- calculating method,
- ground deformation,
- soil convergence model,
- relative depth of tunnel
