| Abstract: | As the differential settlement of composite piled foundation be the subject of research,its' mechanical mechanism,work behavior and deformation property were analyzed and the explicit definition was also given.Through the discussion of several factors which effected on the composite piled foundation,a new disposal manner of piles was provided.The factors,such as raft thickness,length of piles,dimension of piles,distance between piles and so on,brought many affection.In this paper,these affections were studied by Plaxis software. |

| Keywords: | composite piled foundation differential settlement raft the soil rigidity the disposal manner of piles |
