| Abstract: | The article conducted the objective analysis on the collapse and initial lining cracking situation during the tunnel entrance construction of shallow-buried bias section in Baken Tunnel.Combined with the actual construction situation,it proposed the surface rein-forcement and soil bias balancing measures,effectively controlled the surface deformation and tunnel settlement cracking,and ensured the safety and smooth progress of tunnel cons-truction. |
