复合浇筑式沥青钢桥面铺装层力学计算

Mechanical study of steel bridge deck pavement with composite guss asphalt materials

钢桥面铺装的病害在大跨径桥梁上仍然很常见,钢桥面铺装已经成为制约大跨径桥梁发展的一个难题。本文采用有限元法对复合浇筑式沥青铺装层进行受力分析,将正交异性钢桥面板、铺装层作为整体,建立有限元模型,研究铺装层在行车荷载作用下的应力、应变规律。

At present, the diseases of steel bridge deck pavement m long-span bridge are sun very com- mon, and steel bridge deck pavement has become a difficult problem of long-span bridge development. The stress analysis of compound casting type asphalt pavement was made using the finite element method. Taking the orthotropic steel deck and the pavement as a whole, a finite element model was established which can be used to study the stress and strain features of the surfacing layer.
