| 摘 要： | 随着高等级公路的大量建设，超大断面隧道不断涌现。目前对超大断面隧道力学性质与支护结构机理及其施工方法的研究仍然不足。以郑州市中原路西延线韩门超大断面隧道为工程依托，采用有限元分析方法，对超大断面隧道开挖过程进行有限元模拟，揭示双侧壁导坑法与CD法开挖方式下隧道围岩的变形规律、应力分布特征等，为超大断面隧道设计和施工提供理论依据，并通过现场监测予以验证。揭示大断面隧道开挖变形机理，优化施工技术，以指导超大断面隧道设计和施工。

| Abstract: | Along with the construction of high‐grade highway ,so as the large cross section tunnel .At present ,the mechanical properties and mechanism of supporting structure of large cross section tunnel and construction methods of the research is still insufficient . Taking Zhengzhou Zhongyuan road west extension line Hanmen based on the engineering support of large cross section tunnel ,with the method of finite element analysis , for finite element simulation of large cross section tunnel excavation process , reveals the double‐side‐wall pilot tunnel method and CD method excavation method under the deformation law of surrounding rock ,stress distribution characteristics ,etc .Provide theoretical basis for the design and construction of large cross‐section tunnel ,and verified through the field monitoring ,reveal large cross section tunnel excavation deformation mechanism ,and optimize the construction technology ,to guide the design and construction of large cross section tunnel . |
