摘　　要：某国道设计采用隧道方式从小峪沟尾矿库下方21 m深度通过。由于尾矿库属于重大危险源,保证隧道施工和运行不影响小峪沟尾矿库的安全,成为该国道路由方案是否可行的关键。从爆破振动安全影响、采用SLIDE力学分析软件、有限元分析软件Midas4.2对隧道围岩变形及尾矿坝稳定性方面进行模拟并计算分析。其结论该隧道虽然从尾矿库正下方施工并运行,但两者之间都是安全稳定的,为该隧道的路由方案提供了理论支持。A certain national highway is designed to pass through a 21m depth under the Xiaoyugou tailing pond by means of a tunnel.Since the tailings reservoir is a major source of danger,how to ensure that the construction and operation of the tunnel does not affect the safety of the Xiaoyugou tailings pond has become the key to the feasibility of the national highway routing scheme.From the safety impact of blasting vibration,SLIDE mechanical analysis software and finite element analysis software Midas4.2 are used to simulate,calculate and analyze the deformation of tunnel surrounding rock and the stability of tailings dam.The conclusion is that although the tunnel is constructed and operated directly under the tailings reservoir,both are safe and stable,which provides theoretical support for the routing scheme of the tunnel.
