摘　　要：结合我国现行高速铁路规范,依据旅客舒适度控制指标研究400 km/h高速铁路车站两端平面曲线半径与超高的匹配关系。研究结果表明:按单一高速列车或高低速列车共线要求确定最小曲线半径时,推荐、良好和一般舒适度条件对应的临界速度分别为290 km/h、254 km/h和227 km/h,低于临界速度应选择高低速列车共线运行模式,此时过超高允许值、欠过超高之和允许值是影响最小曲线半径取值的关键因素,其中过超高允许值占主导。根据CR400“复兴号”动车组的V-S曲线,为满足曲线半径不大于12000 m的要求,车站两端最小曲线半径宜按良好和一般舒适度标准进行衡量,以保证设计超高同时满足高速列车欠超高和低速列车过超高要求。This paper studies the matching relation between the radius of horizontal curve and superelevation at both ends of a 400 km/h high-speed railway station according to the control index of passenger comfort on the basis of the current highspeed railway specifications in China.The results show that when determining the minimum radius of curve according to the requirements of a single high-speed train or high and low-speed trains on the same line,the critical speeds corresponding to recommended,good and general comfort conditions are 290 km/h,254 km/h,and 227 km/h respectively,and the operation mode of high and low-speed trains on the same line shall be selected when the speed is lower than the critical speed.At this time,the allowable value of surplus superelevation,the allowable value of the sum of deficient and surplus superelevations are the key factors affecting the minimum radius of the curve,among which the allowable value of surplus superelevation is dominant.According to the V-S curve of CR400“Fuxing”electric multiple-unit,in order to meet the requirement that the curve radius shall not be more than 12000 m,the minimum curve radius at both ends of the station should be measured according to the standard of good and general comfort,so as to ensure that the designed superelevation can meet the requirements of deficient superelevation for a high-speed train and surplus superelevation for a low-speed train.
