摘要
通过大型有限元ABAQUS软件,进行三维弹性有限元的数值分析。以9根长桩、4根短桩复合地基为例,研究了在竖向荷载下长短桩复合地基中承台—垫层—桩—土的共同作用特性,对长短桩复合地基的桩体荷载传递规律、桩土应力比、沉降及其影响因素进行了系统的分析,得出了相应的结论。
Presents nine long piles and four short piles composite foundation by using of ABAQUS FEM program,characteristics of co-action among pile cap-padding layer-pile-earth in compostion foundation of pile cluster under vertical loading are studied with three dimensional finite element method;and load transmission characteristics and pile-soil stress ratio,settlement and their influence factors in composite foundation are systematically analysed,corresponding conclusions are drawn.
