半刚性沥青路面车辙三维有限元分析

Three-dimensional finite element analysis of semi-rigid asphalt pavement rutting

基于半刚性基层沥青路面车辙严重现状,利用ANSYS有限元软件建立了三维有限元模型,研究了不同轴载以及不同结构参数下沥青层剪应力的变化规律,为防止半刚性沥青路面车辙破坏提供理论依据。

Based on the serious situation of rutting in semi-rigid base asphalt pavement, three-dimensional model of semi-rigid asphalt pavement is built by using ANSYS finite element software. Axial load and structure parameters on the shear stress of asphalt layer are studied.
