| Abstract: | 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. |
