摘　　要：结合某工程实例,建立湿接法空心板梁有限元实体单元模型,通过比较多种跨度的预制空心板梁混凝土铺装对荷载横向分布系数和挠度的影响情况,揭示了混凝土铺装在该类中小跨度板梁中对结构荷载横向分布系数和刚度的影响。该研究成果可为同类桥梁的结构设计提供参考。Combined with an engineering,the finite element solid element model of the wet-joined hollow slab beam was established.The influence of concrete pavements of precast hollow slab beams with various spans on transverse load distribution coefficient and deflection were compared.The influence on the distribution coefficient and stiffness of the structure were revealed.The results can provide reference for similar bridge structural design.
