摘　　要：以东荣河隧道滑坡为原型,进行了无桩、桩隧间距16 m和桩隧间距22 m三种室内模型试验,研究了滑坡体内压力和位移的变化规律以及隧道衬砌的受力情况。在抗滑桩类型的选择、桩隧间距的确定、抗滑桩设置对隧道稳定的影响以及滑坡推力的分布型式等方面取得了一定的成果,对滑坡地段隧道变形开裂病害的有效整治具有重要意义。Taking Dongronghe tunnel landslide as an example,three model tests,i.e. test without antislide pile,tests with intervals of 16 m and 22 m between antislide piles and tunnel are made in laboratory. The variation regularities of pressure and deformation in sliding mass and the pressure behavior on tunnel lining are studied. The choice of the type of antislide piles,determination of the interval between antislide piles and tunnel,effect of antislide piles on stability of tunnel,and the distribution pattern of landslide-thrust are pointed out. The achievement of the research is important for controlling deformation of the tunnels in landslide field effectively.
