摘　　要：本论文重点对铁路轨道的刚度相关问题进行分析,并对轨道容许变形量、轨道部件容许应力之间的关系,行车舒适性和维修工作量之间的关系,结合其中的情况,提出了能够确定铁路轨道刚度的方法:钢轨允许应力法、轨道允许变形法以及临界速度法三种方法,并且对三种方法的推导过程和原理进行了详细的分析,并且说明了在高铁中不适合使用允许应力法的情况。目前我国的铁路多为有碴轨道,因此也要借鉴国外有碴轨道铺设丰富的经验,并且结合我国铁路的实际情况,与此同时,我国的技术人员也要不断优化确定方法,提高列车行驶的舒适度。This thesis focuses on the railway track stiffness related problems were analyzed, and the allowable deformation, track track components admissible stress relationship, the relationship between the driving comfort and repair workload, combined with the situation, proposed the method for determining the rigidity of railway track： rail, rail allows the allowable stress method deformation and critical speed by three methods, and the derivation process and principle of the three kinds of methods are analyzed in detail, and that the Gao Tiezhong is not suitable for the use of the allowable stress method. At present our country railroad for the ballasted track, so we should learn from foreign experience laying ballast track,and combined with the actual situation, the railway of our country at the same time, the technical personnel of our country must also continue to optimize, improve the running comfort.
