| Abstract: | For shield tunneling in the soft-soil area,in view of the soil mass failure and creepage caused by shield tunneling entry,during the construction of the tunnel between Liyang Road station and Quyang Road station of the Shanghai Rail Transit Line No.10.soil freezing reinforcement method was applied to the shield tunneling entry and acquire better result.This article studies the project from the choice of reinforcement scheme,key technologies and actual monitoring to provide reference for similar projects. |
