基于ANSYS的桥梁全桩基础的三维有限元仿真分析

Three-dimension Finite Element Simulation Analysis on Full-pile Foundation of Bridge Based on ANSYS

桥梁基础是桥梁结构工程的一个重要组成部分,它承担着上部结构的重量和外部作用力,并将其传给地基。该文基于有限元软件ANSYS就桥梁全桩基础进行三维仿真分析,包括桥梁全桩基础的构造设计、建模与网格划分、在自重和汽车活载作用下的受力分析。

The bridge foundation is an important composed part of bridge structural engineering.It bears the weight of the upper structure and the external force,and conveys them to the subgrade.Based on the finite element software ANSYS,the article carries out the three-dimension simulation analysis on the full-pile foundation of bridge,including the constitution design,modeling and network division of the full-pile foundation of bridge,and the stress analysis under the dead weight and vehicle live load.
