钢桥面铺装对移动荷载的动态响应研究

Research On Dynamic Response of Steel Bridge Deck Pavement to Moving Load

通过建立钢桥面铺装体系力学分析模型,对以一定的速度移动的车辆荷载,钢桥面铺装层的受力影响进行数值模拟。分析了铺装体系在不同车速行驶的车辆移动荷载作用下的横向拉应力、纵向拉应力、表面竖向位移、剪应力和相同车速下铺装层剪应力等受力特性。最后得出的结论可以为进一步分析桥面铺装问题提供理论参考。

The mechanics analysis model of steel deck pavement system is established to make a numerical simulation of the moving vehicle load with certain speed and the stress influence of the pavement. Several stress features of the pavement system under the moving vehicle load with different speed are discussed in this paper including transverse tensile stress, longitudinal tensile stress, surface vertical displacement, shearing stress and the paving layer shearing stress under the same speed. The conclusions can provide reference for further analysis of deck pavement.
