Abstract:Seismic performances of anti-slide piles with anchor cables are the basis for establishing and improving their seismic design method. To reveal the seismic behaviors of anti-slide piles with anchor cables,the project of anti-slide piles with anchor cables reinforcing the Beihou mountain landslide was taken as the reference prototype,and the corresponding 50 g model on centrifugal shaking table for simulating the prototype performances was built. The bedrock waves at Qingxi station during the Wenchuan earthquake were exerted as the base excitation in the model tests. The historic data of accelerations on the surface and inside the landslide reinforced by anti-slide piles with anchor cables,the strains of pile,the dynamic soil pressures between the landslide body and the anti-slide piles and the axial forces of anchor cables were recorded. The variations of landslide accelerations,bending moments of anti-slide,dynamic soil pressures between the landslide body and the anti-slide piles,axial forces of anchor cable were revealed from the above data.
