Dynamic Response Analysis of Stress in Asphalt Concrete Pavement Structure Under Vehicle Load
Author(s): 
Pages: 13-18
Year: Issue:  6
Journal: Highway

Abstract: 借助大型有限元软件ABAQUS,运用三维动力有限元的方法,建立了移动荷载作用下基于土基横观各向同性的沥青混凝土路面结构的三维仿真模型,并编制了Dload和Utracload子程序来施加移动荷载.通过有限元Standard计算模块,分析和比较了移动荷载下车辆正常行驶、减速和加速情况时路面结构内部应力响应规律.分析结果表明:在移动荷载作用下,路面结构的面层主要处于三向受压状态;减速和加速情况时的垂直应...
