摘要
采用ABAQUS有限元软件对高速公路拓宽后新老路基差异沉降进行了数值模拟,分析了加宽方式、加宽宽度、加宽高度、路基刚度、路基填料重度、土基模量、软土地基深度等各种因素对地基及新老路基附加沉降的影响,为高速公路拓宽工程的设计与施工提供参考。
Numerical simulation of differential settlement of subgrade were made for the widening project of expressway by using ABAQUS finite element software. The analysis on additional settlement in ground and subgrade influenced by widening way, the width of widening subgrade, the height of widening subgrade, subgrade modulus, the density of subgrade fill, soil base compressive modulus and the depth of soft soil foundation were carried out, which can provide reference for the design and construction of widening project of expressway.
