基于府店路荷载调查资料,探讨了我国疲劳车辆模型的建立方法。将疲劳车辆加载于常用跨径简支梁桥上,分析比较了各疲劳车辆的疲劳损伤。通过定义疲劳损伤率,评估了各疲劳车辆的等效精度。在我国疲劳设计车辆尚未建立的情况下,建立疲劳车辆的方法对我国公路桥梁的疲劳设计具有一定的指导意义。
Based on on-site survey from Fudian Road,methods are explored to establish a fatigue truck model.The load-effects of common simple-span bridges are computed,fatigue damage of various vehicles are analyzed and compared.Fatigue damage rate is defined to assess the accuracy of fatigue trucks.Considering that fatigue truck hasn't set up yet,the method in the paper may be helpful in fatigue design of Highway bridge.
