Abstract

Supporting structure of double-row piles in deep foundation was analyzed by 3-D finite element on the base of some case study. Some factors are changed such as array pitch, pile stiffness, soil properties in piling and passive area. There are other factors that are taken into account such as spatial coordination role of coupling beam and interaction between pile-soil. The deformation and stress of double-row piles in deep foundation was analyzed and the excavation process was simulated by flac3D. Through analyzing the displacement alteration, we can concluded that combining various measures and reducing structure deformation may optimize structure design of double-row piles.
