将滑动方向在隧道轴线方向投影与隧道轴线平行的滑坡体定义为平行隧道滑坡体,将穿越这样的滑坡体的隧道称为平行穿越滑坡体隧道。滑坡体会使隧道结构发生整体滑移、开裂变形,严重时还会使其失去承载能力以致造成坍塌等事故,首先讨论了平行穿越滑坡体隧道二次衬砌的受力模式,运用荷载结构法计算了二次衬砌的内力,以此探讨其结构的稳定性。最后,通过工程案例的分析,得出了平行穿越滑坡体对该隧道二次衬砌的安全稳定影响,可指导类似工程的施工和安全评估工作。
A landslide body whose sliding direction is projected parallel to the tunnel axis in the direction of the tunnel axis is defined as a parallel tunnel landslide body, and a tunnel crossing such a landslide body is called a parallel crossing tunnel of a landslide body. Landslide will cause the whole structure of the tunnel to slip, deform and deform. In severe cases, the landslide will lose its carrying capacity so as to cause collapse and other accidents. The stress modes of the secondary lining of parallel tunneling through landslide tunnels are discussed first, and the load structure method is used to calculate The secondary lining of internal forces, in order to explore the stability of its structure. Finally, through the analysis of engineering cases, the safety and stability of the secondary lining of the tunnel passing parallel to the landslide body are obtained, which can guide the construction and safety assessment of similar projects.
