桥基参数对承台和桩及土的影响分析

Impact analysis of bridge foundation parameters on caps and pile and soil

通过ABAQUS程序建立三维非线性有限元模型,分析了在不同承台厚度、不同桩身弹性模量、不同土体变形模量等参数作用下对承台中心处总沉降、桩土荷载分担比、土中附加应力等基础的工作性状的影响,得出了相应的变化规律,为实际工程中复合桩基的设计提供指导,使设计更加经济合理。

This paper establish 3D none linearity finite dement model by ABAQUS program to analyze the infection of settlement in centre of platform, percent of load for pile and soil, addition stress in soil when the thickness of platform is different, elastic modulus of pile is different, soil deformation modulus is different, drawing the corresponding rule to provide guidance for the actual engineering design of composite pile foundation, to make design more economical and reasonable.
