摘　　要：新的桥梁设计规范中汽车荷载的较大改变使得长悬臂行车道板的计算有所变化。文章结合新旧桥规的相关规定以及长悬臂行车道板计算理论,对行车道板内力进行分析并对结果进行了比较,得到了一些相关计算中应该引起注意的结论。The big change of the vehicle load in the new code of bridge design brings about some changes in the calculation of the large cantilever deck. Based on the terms in the new and old codes and the theory of the large cantilever deck, the internal force of the deck is analyzed, and the calculation results of two examples are compared. Some points which should be considered in the calculation are presented.
