摘要：

为研究轮载作用下正交异性钢-混组合桥面结构的竖向传力机制，提出横桥向的轮载扩散效应理论模型，并基于既有模型试验进行有限元分析，验证所提出的理论模型并进行参数分析。结果表明：与传统45°角均匀扩散假设不同，重载双轮作用下钢顶板横桥向上的压应力主要分布于轮载作用区域两道U肋范围内，轮载分担率可通过以U肋腹板为支点的三跨简支梁模型得到。常用设计参数取值范围内，提出的正交异性组合钢桥面的轮载分担规律偏保守，可为设计参考。

Abstract:

A theoretical model is proposed for the wheel-load diffusion to investigate the transmission mechanism of vertical loading on the steel-concrete composite bridge deck system under local wheel loads. An existed full-scale test model was referred and the corresponding finite element numerical simulation were also conducted to verify the presented model and analysis the key parameters. The results show that， rather than the traditional assumption of 45 degree diffusion effect， the pressure on the steel top plate of the composite deck under vehicle loads has a significant local effect along the transverse direction of U-rib， and the sharing law of the wheel load could be obtained from the 3-span beam simply supported by the webs of U-rib. The paramelric analysis shows that， the proposed theoretical model is conservative in the common value range of engineering parameter of orthotropic steel-concrete composite bridge deck， and it could be referred to the design of orthotropic composite bridge deck.

Key words: bridge engineering, orthotropic steel-concrete composite bridge deck, wheel load, diffusion angle, concrete overlay
