Construction Analysis of Municipal Tunnels with Super Large Cross-section and Shallow Buried Weak Surrounding Rock
With the gradual improvement of municipal road engineering,the tunnel section continues to increase,often facing construction conditions of super large section shallow buried weak surrounding rock,which puts forward higher requirements for tunnel construction.This article analyzes common construction methods and provides a detailed explanation of tunnel construction methods in conjunction with a certain engineering project.By establishing models of double-sided wall heading method and cross middle partition method,the two methods are compared,focusing on monitoring surrounding rock displacement,controlling support deformation and ground settlement,and selecting the best construction method.
