Static and Dynamic Test Analysis of Bearing Capacity of Rigid Pile Composite Foundation

According to similarity theory,this paper established rigid pile composite foundation pile group model.The deformation characteristics,force characteristics of piles and soil of rigid pile composite foundation are tested.Static test shows that: cushion can adjust pile-soil load share ratio,stress of different pile spacing pile.The biggest is the corner pile,next is the side pile,and the smallest is the center pile.And it studied distribution characteristics of the bending moment and shear value with pile and displacement time history of the flask.Dynamic test shows that: whether bending moment or shear is in investigation the biggest is the corner pile,next is the side pile,and the smallest is the center pile.It is concluded that rigid pile composite foundation has excellent seismic behavior.
