| 摘 要： | 基于汽车对桥面的动力作用,对典型的沥青混凝土桥面铺装结构建立了线弹性三维有限元模型,运用动力学基本理论和有限元方法,分析了移动荷载作用下桥面柔性铺装层竖向变形、主拉应力和最大剪应力的时程响应规律,并研究了不同车速和超载水平对桥面柔性铺装层的力学指标的影响规律,为沥青混凝土桥面铺装的研究提供了有力的支持。

| Abstract: | Based on the dynamic action between vehicle and bridge deck,3D finite element model is developed for typical asphalt pavement of bridge deck.This research based on the basic theory of dynamics and finite element method,in order to obtain the results of vertical deformation,principal tensile stress and maximum shear stress under moving load.The mechanical regularity impacted by vehicle speed and overloading are compared.Finally,some support for bridge deck pavement research is offered. |
