Based on the static and dynamic centrifugal model test of cantilever anti-slide pile in accumulation landslide

the mechanical characteristics of anti-slide pile and the seismic responses of landslide were analyzed using data from soil-pressure sensors

strain gauge pairs of pile and accelerometers. The results show that the distribution laws of earth pressure on the back of piles and bending moment of pile under static loading and dynamic conditions were different. The static earth pressure of pile back was significantly greater than that induced by earthquake action

but the static bending moment of pile was far smaller than that caused by seismic vibration. The dynamic earth pressure on the back of piles and the bending moment of piles increased with the increase of peak ground motion. The action points of the maximum earth pressure on the back of piles and bending moment of pile were lower under seismic actions than under static condition. There is superficial amplification effect near the crest of landslide and elevation magnifying effect inside the landslide. The phenomenon of wave type transform was significant

to which more attention should be paid in aseismatic design.
