群桩基础的精细化设计模拟

大跨径桥梁以及上下部刚构的桥梁对下部结构刚度敏感性很高,如何对桥梁结构整体进行精细化模拟,以求得到精确的结构反应解答,对现代桥梁设计至关重要。其中群桩基础的有效模拟对整个下部结构刚度尤为重要。针对影响桩基础有限元模拟的关键因素进行分析,以求找到影响桩基有限元模拟精度的因素,为群桩基础的有限元精细化模拟提供参考。

Simulation of Refinement Design of Group Pile Foundation

The long-span bridge,the super and lower-rigid-frame bridges are highly sensitive on the substructure rigidity.It is extremely important for the design of the modern bridges in how to carry out the refinement simulation of the integral bridge structure in order to get accurate structural response,in which the efficient simulation of group pile foundation is mostly important for the integral substructure rigidity.The article analyzes the key factors to influence the finite element simulation of pile foundation in order to find the factor to influence the finite element simulating accuracy of pile foundation,which can be referred for the finite element refinement simulation of group pile foundation.
