Study on DJM pile composite foundation with numerical simulation method

With the foundation of the Shanghai Taopu Xincun building as the engineering background, this paper study the stress and condifions: deformation of the DJM piles composite foundation with the numerical simulation method under following conditions: when the piles are in equal length, the piles are not in equal length, the concrete amount of the lower part of the piles has been reduced, and there are different spaces between piles. The authors put forward the optimum design method for the DJM piles composite foundation based on the study results which have been adopted in designing.
