摘　　要：为了进一步了解半刚性基层沥青路面在移动行车荷载下的力学响应,以浙江某高速公路为背景,利用MIDAS GTS软件建立了全断面三维有限元模型,采用标准轴载BZZ-100对轮胎接触面积内的路面施加移动行车荷载,对路面结构各层竖向位移、正应力和剪应力的分布及变化规律进行了分析研究,研究成果可以为半刚性基层沥青路面的建设和运营提供参考。In order to learn more about the mechanical response of semi-rigid asphalt pavement under moving driving load,based on a highway in Zhejiang Province,a 3D finite element model of the full section is established by MIDAS GTS software,which adopts the standard axle load BZZ-100 as moving driving load on the pavement in the tire contact area.The distribution and variation of vertical displacement,normal stress and shear stress of each layer of the pavement structure are analyzed and studied,which can provide reference for construction and operation of semi-rigid base asphalt pavement.
