摘　　要：钢桥面铺装层的沥青混合料具有明显的粘弹塑性材料力学特性 ,应用Perzyna理论 ,对沥青混合料铺装层行车荷载响应特性进行数值模拟 ,给出铺装层在行车荷载作用下的永久变形 ,对铺装层的局部拥包及车辙等现象进行评价 ,结果与M RAsphalt mixtures of steel bridge pavement has obvious mechanical characteristics of visco-elastoplastic materials. By applying Perzyna's theory to the constitutive equations, the responses of pavement to the vehicle loads was modelled numerically. The permanent deformations in pavement were obtained, the phenomenon of swelling and rutting in pavement was evaluated. Good matches were found between those from this paper and M.R. Thompson's results.
