【摘要】 为填补目前木拱廊桥在结构简化设计方法上的空缺。文中基于其结构特点，建立了相应的简化模型并提出了一种结构内力计算方法。通过与有限元分析结果比较发现，该简化模型及计算方法能够较为准确地计算牛头处接触压力、苗杆弯矩、苗杆轴力，相比于有限元模型在保证计算精度的同时效率更高，该方法为木拱廊桥主拱结构设计提供了参考。更多还原

【Abstract】 To fill the gap in the structural simplified design method of the wooden-arched corridor bridge in China.Based on the structural characteristics, this paper establishes the corresponding simplified model and puts forward a calculation method of structural internal force. Compared with the finite element analysis results, the simplified model and calculation method can accurately calculate the contact pressure at the cow head, the seedling rod bending moment, and the seedling rod axial force. Compared with the finite element model, it has higher efficiency while ensuring the calculation accuracy. This method may provide the reference for the main arch structure design of similar bridges.更多还原
