| 摘 要： | 通过对广州市内环线恒福路段交通情况的实地调查，依据等效疲劳损伤原理，将实测的车辆荷载频值谱简化为由疲劳荷载模型车辆组成的实用频值谱，得到了由日常运营车辆组成的荷载频值谱．根据车辆组成的荷载频值谱，建立了广州市高架桥疲劳荷载车辆模型．所建立的疲劳荷载车辆模型，可供广州市其他高架桥梁疲劳损伤验算或疲劳设计时参考．

| Abstract: | Based on the survey of the traffic conditions at t he Hengfu Road section of the Guangzhou Inner Ring Road, the load frequency value spectrum composed of daily transport vehicles was obtained by simplifying the observed load frequency value spectrum into a practical one composed of model vehicles according to the principle of equivalent fatigue damage. The fatigue-loaded vehicle model of Guangzhou trestle bridges was then set up on the basis of the simplified load frequency value spectrum. This model can be applied as a reference to the fatigue assessment and design of other trestle bridges in Guangzhou. |
