Introduction：
Computational model for analyzing the stability of continuously welded rail track on raising speed railway is developed by means of the finite element method in this paper, in which track panel including rails, ties, rail fastenings and ballast resistances as a whole system, and non-linear deformation behavior of rails under temperature stress are considered. Based on the model, numerical computational formulas are induced and programmed. Influences of the lateral resistances of the ballast, invalid ties and curved track radius as well as initial flexural deformations on the stability of continuously welded rail track are investigated.
简介：
计算模型分析高速铁路的提高是通过在这个文件，有限元方法开发了无缝线路的稳定性，其中包括铁路轨道面板，领带，铁路扣件和整个系统的镇流器电阻，和非钢轨下的线性变形行为被认为是温度应力。基于该模型，数值计算公式，诱导和编程。镇流器的，无效的联系与曲线轨道的横向阻力的影响半径以及对无缝线路稳定性的初始弯曲变形进行了研究。
