摘　　要：针对我国公路桥梁设计规范暂无疲劳荷载规定的情况,参考英国桥梁规范BS 5400和疲劳研究成果,根据疲劳积累损伤理论,以重庆石板坡长江大桥钢-混凝土结合段疲劳试验荷载的确定为例,对公路桥梁疲劳荷载的确定方法和原则进行了研究,并给出了具体的推算方法。Taking the determination of fatigue test load for the steel and concrete joint part of Shibanpo Changjiang River Bridge in Chongqing as an example, this paper makes a study of the method and principle of determination of fatigue load for highway bridges and also provides specific ways of calculation in compliance with the fatigue accumulative damage theory with reference to the British Standard BS 5400 and relevant fatigue research findings in the absence of fatigue load provisions in the current highway bridge design specifications in China.
