摘　　要：该文以2跨及3跨25m后张法连续板桥的设计为例,分析了在跨数较少的情况下连续墩墩顶负弯距区的受力特性,并对这一特性进行了详细的比对计算,有关内容可供同类型桥梁设计时参考。Taking the design of 2-span ～ 3-span 25-m post-tensioning continuous plate bridge as an example,the article analyzes the stress characteristics of negative moment area at the top of continuous pier under the condition of a few piers,and contrasts and calculates this characteristic in detail.The relative contents can be referred for the design of the same bridges.
