摘　　要：为探究UHPC-NC-钢板组合桥面板抗正弯极限承载能力并提出桥面板合理构造,本文通过对7块不同UHPC层和NC层厚度的UHPC-NC-钢板组合桥面板进行Abaqus有限元模拟,对比了其在正弯矩作用下的荷载-挠度曲线、应力云图等数据,分析了UHPC层和NC层厚度变化对桥面板承载能力的影响,提出了抵抗正弯矩作用时UHPC-NC层厚度的优化思路,可供施工设计时灵活选用。In order to explore the ultimate bearing capacity of UHPC-NC-steel plate composite bridge deck against normal bending and propose the rational structure of the bridge deck,this paper conducts Abaqus finite element simulation of seven UHPC-NC-steel plate composite bridge decks with different UHPC layer and NC layer thicknesses,and compares the load-deflection curves under positive bending moment.The influence of the thickness change of UHPC layer and NC layer on the bearing capacity of the bridge deck was analyzed,and the optimization idea of UHPC-NC layer thickness resisting the action of positive bending moment was proposed,which can be flexibly selected in construction design.
