摘　　要：以沉降控制复合桩基差异沉降为研究对象,给出了差异沉降的明确概念;通过对复合桩基差异沉降的各种影响因素的讨论,提出了控制差异沉降的新的布桩方式,并运用有限元法分析了筏板厚度及桩长、桩径、桩距等因素对差异沉降的影响。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.
