摘　　要：针对工程中混凝土桥面板和钢桥面板的结构特点和具体使用状况,提出了一种钢与混凝土组合桥面板。通过对截面参数的优化,得到合理的组合桥面板截面形式。与混凝土桥面板和钢桥面板的受力对比分析,从理论上验证了正交异性钢板-混凝土组合桥面板应用于某些工程可行性。采用足尺桥面板的加载试验,得到了组合桥面板的抗弯极限承载力为规范车辆荷载效应的5.67倍,证实了其应用到桥梁结构中具有较大的安全储备。根据试验结果,在正常使用阶段可以按照平截面假定计算组合桥面板受力性能。According to the structural characteristics and the specific used situation of both concrete bridge decks and steel bridge decks, a new type of steel and concrete composite bridge deck was presented. A reasonable section form of the composite bridge deck has been attained through the optimization of the main parameters of the composite section. The comparison between the bearing loads of the composite bridge deck, the concrete deck and the steel deck is conducted by theoretical analysis. It is demonstrated that it is feasible to use the orthotropic corrugated steel plate and concrete composite bridge deck on some projects. The full-scale loading test proves that the bending capacity of the composite bridge deck is 5.67 times that of the vehicle load action capacity in the current specification, which shows that considerable safety reservation was retained in the deck system by adopting the composite bridge deck. Based on the experimental results, the load behavior of the composite bridge deck in the serviceability limit state can be calculated according to the plane section assumption.
