摘要
Combined with a large-scale project, the large stress ratio test to the DJM pile composite foundation in the soft clay of Chengdao was conducted. The regulations of the pile-soil stress ratio of DJM pile composite foundation with the change of load, time, thickness and stiffness of pillow in Chengdao region were obtained. The finite element analysis was carried out, and these two results were compared. The results show that there is no time effect to the pile-soil stress ratio of DJM pile composite foundation. The pile-soil stress ratio of DJM pile composite foundation is negative correlation to the thickness of pillow.
