摘要
结合郑西客运专线凤凰岭隧道和高桥隧道的施工,通过对现场监控量测数据分析,总结了大断面湿陷性黄土隧道施工中弧形导坑法、CRD法、双侧壁导坑法的不同适用范围,指出其具体施工工艺步骤、质量控制要点及围岩的变形规律,同时指出隧道洞内基底湿陷性处理的措施。
In light of Fenghuangling Tunnel and Gaoqiao Tunnel Construction of Zhengzhou-Xi' an PDL,this paper summarizes different applicable areas of arc heading method,CRD method and double-side-wall heading method,by analyzing field monitoring data.Concrete construction processing steps,quality controlling points and surrounding rock deformation rules are pointed out,together with measurements for treating basement collapsibility in tunnel cave.
