中文摘要：
高速铁路线路平纵断面参数对高速行车安全性与舒适性有较大的影响，从动力学角度对线路平纵断面参数设计合理性进行校核是必要的。为了对高速铁路线路平纵断面设计安全性与舒适性进行评估，本文基于机车车辆与线路最佳匹配设计原理，采用车辆-轨道耦合动力学仿真技术，提出了一套切实可行的评估方法。作为工程应用实例，结合京沪高速铁路工程实际，对京沪高速铁路线路平纵断面进行了全面的行车安全性与乘车舒适性分析评估。
英文摘要：
The parameters for plan and profile of high speed railway line have great influence on running safety and riding comfort of high speed train and hence it is necessary to check the reasonable dynamic parameters for plan curves and vertical profile curves of line. For better assessment, this paper presents a set of feasible assessment method of which the simulation technique of vehicle-track coupling dynamics is employed based on the optimum matching design principle between railway vehicles and tracks. Such proposed method is successfully applied for assessing the design parameter of the plan curves and vertical profile curves of the Beijing-Shanghai high speed railway.
