移动荷载下钢桥面铺装表面拉应力粘弹性分析

Analysis on the Tensile Stress Viscoelasticity of Paved Surface on Steel Bridge Deck under Moving Load

文章针对钢桥面铺装体系受力复杂、铺装表面承受较大的弯拉应力、钢桥面铺装使用的荷载与温度条件相对恶劣等情况,对钢桥面沥青铺装表面的拉应力进行了粘弹性有限元计算分析,介绍采用粘弹性材料模型,利用试验数据计算得到的材料计算参数,为铺装设计提供参考。

Considering that the steel bridge deck syste m is subject to complex force,the paved surface bears large bending force,and the load and temperature condition on the steel bridge deck is relatively bad,a viscoelasticity finite element calculation and analysis has been made for the t ensile stress of asphalt pavement on steel bridge deck. The article shows how to obtain calculative parameters by means of viscoelasticity material model and te st data. It provides reference for pavement design.
