水泥混凝土桥桥面铺装结构组合方法分析

摘要

In this paper, finite element models of three different type bridges are built, demonstrating the mechanical impact of the pavement layer thickness on bridge deck system. It is indicated that long-span concrete bridge deck system is less influenced by the pavement layer thickness. Therefore, it is proposed that structural combination design should be more consideration from the performance of bridge deck materials.%建立了三种不同桥型的有限元模型，论证了铺装层厚度对铺装体系受力的影响，得出大跨径水泥混凝土桥铺装体系受铺装层厚度的影响较小，并建议结构组合设计应更多地从铺装层材料功能角度上考虑。
