摘要

摘要: 目前已有大量针对曲线桥主梁建模方法的研究，但其实用性仍存在一些不足，特别是缺乏针对不同下部结构形式的主梁数值模拟方法适用范围的探讨。该文以京开立交某匝道桥为工程原型，建立不同曲率半径、桥面宽度以及下部支承形式的曲线桥主梁数值分析模型，并以曲线桥边墩支座变形及中墩墩底剪力作为关键结构响应，探讨单梁法、脊梁法、梁格法模型在桥梁地震反应中的误差规律。该文研究结果针对不同类型曲线桥的主梁建模方法提出了合理化的建议，对曲线桥在抗震设计中提高建模的精度和效率具有重要意义。

Abstract: At present, a lot of researches on the modeling method of the main girder of the curved bridge have been carried out, but its practicality still has some shortcomings, especially lack of the numerical simulation method of the main girder under different lower parts of the structure. Based on the Jing-Kai overpass, this paper establishes a numerical model of the main girder of the curved bridge with different radius of curvature, bridge width and lower support form. Furthermore, the error law of the single-girder method model, the spine method model and the grillage method model in the bridge earthquake response is discussed by using the deformation of side support and middle pier shear as the key structure. Advices for the main girder modeling method of different types of curved bridges are proposed, which are helpful to improve the modeling accuracy and efficiency in the seismic design of curved bridges.
