【Abstract】 Based the idea of optimization design of pile, the soil-cement pile and CFG pile composite foundation, the cast-in-place pile composite foundation are designed. Through large scale model test, the dynamic characteristics and the rule of dynamic response and its influencing factors about the cast-in-place pile composite foundation is researched. the cast-in-place pile composite foundation is researched. Get regular pattern between the load and frequency and acceleration.更多还原
