新建及拓宽公路路堤挡土墙受力及变形有限元分析

Finite Element Analysis of Stress and Deformation of New and Widened Highway Embankment Retaining Wall

为了解新建及拓宽公路路堤挡土墙受力及变形特性,以某高速公路改扩建项目为例,采用ABAQUS有限元软件,对拓宽公路路堤挡土墙受力和变形特性进行了模拟,并与新建公路路堤挡土墙的模拟结果进行对比分析,为今后已建高速公路改扩建项目路堤挡土墙设计提供了有益的参考。

In order to understand the construction and widening of highway embankment retaining wall stress and deformation characteristics,based on a highway expansion project as an example,using ABAQUS finite element software,the widening of highway embankment retaining wall stress and deformation characteristics are simulated,and simulation of the retaining wall and the new highway embankment results were analyzed.For the future of built highway expansion project provides a useful reference to the design of embankment retaining wall.
