目前世界上其他国家对桥上无缝线路均未考虑挠曲力,我国无缝线路专题组已提出考虑这项重要的设计因素,并通过实验与理论分析,提出了一套挠曲力的计算方法。但其方程的建立方法甚繁,且前一荷载位置的挠曲力对于下一荷载位置挠曲力的影响,现有的挠曲力计算理论还未能解决。本文先就这些方面进行讨论,进一步完善挠曲力的计算理论,然后分析伸缩力与挠曲力的联合作用。
At present, other countries in the world have not considered the flexural force on the seamless track on the bridge. China’s seamless line project group has proposed to consider this important design factor, and through experiments and theoretical analysis, put forward a set of flexural force The calculation method. However, the method of establishing the equation is very complicated, and the influence of the flexural force at the previous load position on the flexural force at the next load position, the existing theory of flexural force calculation has not been solved yet. This article first discusses these aspects to further improve the calculation theory of flexural force, and then analyze the combined effect of flexural and flexural forces.
