基于有限元法的混凝土梁桥沥青铺装结构力学分析

Mechanical Analysis on Asphalt Deck Pavement Structure of Concrete Beam Bridge with Finite Element Method

以高速公路混凝土梁桥沥青混凝土桥面铺装为研究对象,以弹性力学为理论基础,采用ANSYS有限元软件建立了混凝土梁桥沥青混凝土桥面铺装整体结构模型,将实体子午线轮胎模型运用到桥面铺装结构分析中,同时考虑了轴重和胎压对结构受力的影响,研究了多因素条件下混凝土梁桥沥青混凝土桥面铺装结构的应力敏感性,为复合桥面铺装结构设计提供参考依据。

This paper, taking the asphalt concrete bridge deck pavement of expressway concrete beam bridge as the study object, by using elastic mechanics theory, use ANSYS finite element software to build up overall struc- tural model of asphalt concrete bridge deck pavement of concrete beam bridge, with solid tire model being ap- plied to the analysis of bridge deck pavement structure, taking into account the influence on the structure stress by axle load and tire pressure, the stress sensitivity of asphalt concrete bridge deck pavement of concrete beam bridge under multi -factors condition has been studied, which could provide references for the composite bridge deck pavement structure design.
