摘要
针对霍永高速公路东段耿家庄隧道在开挖支护过程中掌子面发生坍塌,衬砌发生大变形及地表开裂等现象,结合隧道开挖段落的地质状况、衬砌支护、施工工艺等情况分析其塌方和变形的原因,提出了详细的处治措施,并对此类隧道施工提出几点建议。
According to the collapses of tunnel faces,large deformation at lining,and ground surface cracks in the excavation and support process of Gengjiazhuang Tunnel along Huozhou-Yongji Expressway,the paper analyzes the reasons for the collapses and deformation from the geological status,lining support,and construction craft of the tunnel excavation sections,indicates some detailed treatment measures,and points out suggestions for similar tunnels.
