| 摘 要： | 桥头搭板设置的目的是为了实现刚柔过度,搭板一端置于桥台牛腿上,一端置于桥头引道路基上.根据桥头搭板的实际受理特点,分别按简支梁（或板）受力模型和部分脱空的弹性地基梁受力模型对搭板进行配筋设计比较,从而得出桥头搭板的配筋设计方法.

| Abstract: | The approach slab is provided to achieve the transition from rigidity to flexibility and vice versa,with one of it on the abutment corbel and the other end on the subgrade of bridge approach. This paper tries to make a reinforcement design comparison between the mechanical model of simple- supported beam/slab and that of partly-hanging elastic foundation beam in pursuance of the real mechanical features of an approach slab, based on which to obtain a scientific and rational design method of reinforcement of approach slab. |
