Analysis of Surface Settlement and Influencing Factors in the Guiyang Metro Tunnel
This study investigates the surface settlement caused by tunnel construction in the context of the Guiyang Metro project using finite element simulation.Through orthogonal numerical simulation experiments,the influence of factors such as tunnel burial depth,stratum elastic modulus,Poisson's ratio,cohesion,and internal friction angle on surface settlement was studied.The results indicate that the influence of elastic modulus,tunnel depth,internal friction angle,Poisson's ratio,and cohesion on the maximum surface settlement decreases sequentially.Tunnel burial depth has the most significant influence on the settlement trough width coefficient,while the influence of stratum parameters on the settlement trough width coefficient is relatively minor.The research findings can provide a reference for similar projects.
