摘要在滑坡地段修建隧道，不可避免会遭受滑坡影响。目前关于隧道–滑坡相互作用机制研究较少，滑坡段隧道开挖方法以及加固措施尚未受到工程界的足够重视。以隧道–滑坡平行体系为研究重点，提出隧道–滑坡体系预加固机制及设计理念。以武罐高速公路阳坡里隧道为原型，建立地质力学模型研究工程预加固和工艺预加固的作用机制，试验研究隧道–滑坡体系在有预加固工程和没有预加固工程条件下正向、反向开挖时的滑坡位移、稳定性变化规律。试验结果表明，隧道开挖方向对滑坡稳定性有一定影响，合理的开挖方向有利于滑坡稳定；加固工程对抑制滑坡变形具有非常好的作用，隧道开挖后滑坡开始变形，滑坡推力逐渐向加固结构转移，使得滑坡后续的位移量远比未加固时小。

Abstract：When tunnels are constructed in landslide area，it would be inevitably to suffer from landslide impact. At present，few studies force on the interaction mechanism of tunnel-landslide. The tunnel excavation method has not been considered seriously by engineering as well as reinforcement measures. Focusing on the tunnel-landslide parallel system，pre-reinforcement mechanism and design philosophy of tunnel-landslide system are proposed. Taking Yangpoli tunnel on Wuhan-Guangzhou highway as a prototype，geomechanical model used to study the mechanism of engineering pre-reinforcement and processing pre-reinforcement is established. The variation of displacement and stability in tunnel-landslide system are explored carefully while excavating forward or reverse in the engineering pre-reinforcement condition as well as without pre-conditions. The test results show that the tunnel excavation direction has some impact on landslide stability that reasonable excavation direction is favorable. Reinforcement project has a very good role in the inhibition of landslide deformation. Landslides began deformation along with tunnel excavation，and the landslide thrust transfers gradually to reinforcement structure making the subsequent landslide displacement less than that unreinforced.
