MODEL TESTING RESEARCH ON CONTROLLING TUNNEL DEFORMATION IN LANDSLIDE FIELD WITH ANTISLIDE PILES
用抗滑桩整治滑坡地段隧道变形的模型试验研究

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.
