摘要
在软土中进行了桩的轴向动静力受压模型试验 ,对桩的动承载力、桩动侧阻、动端阻、桩顶竖向累积位移、桩顶振动位移幅值及动刚度进行了分析研究 ,得到了软土地区高速铁路桥梁桩基承载力设计值应折减 10 %～ 3 0
Model pile tests under dynamic and static load in soft soil have been done,and research is accomplished on dynamic bearing capacity, dynamic side resistance,dynamic end resistance and dynamic stiffness of pile, accumulation and amplitude of displacement on top of pile.It is concluded that bearing capacity of pile foundation of high speed railway bridge must be reduced by 10 percent to 30 percent.
