摘要
为揭示桥上无缝线路梁轨相互作用的规律,应用大型通用有限元软件建立有限元模型,进行大量的计算分析。将分析结果与西南交通大学的研究成果进行对比,验证本计算模型的正确性与合理性。根据计算结果找出桥梁下部结构纵向水平刚度与钢轨力之间的规律。
To study the interactive regulation of beam and rail of seamless route bridge, a FEM model is established. And the FEM calculation results are compared with the study achievement which Southwest Jiaotong University made to prove the FEM model's rationality and validity. Based on the calculation results, the relationship between the longitudinal horizontal rigidity of the bridge lower structure and the force of steel rail is given out.
