Abstract

Abstract

Based on the theory of track-bridge interaction, the calculation model of longitudinal force for continuous welded rail (CWR) on cable-stayed bridge was established, and the related calculation software was compiled.Taking a double-tower steel truss cable-stayed bridge commonly used in the railway as an example, the longitudinal force regulations of CWR were analyzed.Analysis result shows that the cable-stayed bridge can be simplified as a continuous beam with fixed bearing in the middle to calculate rail expansion forces.Rail bending forces can be calculated under the conditions of loads laid on main span and its adjacent span or the separate main span, and the direction change of train needn't be considered.Speed locking devices should be set on railway cable-stayed bridge to effectively limit the main beam longitudinal displacement under train braking force, and rail deformation decreases simultaneously.The method of trackbridge interaction should be used for cable-stayed bridge with CWR to calculate rail broken gap value accurately.
