【摘要】 针对高速铁路无越行区段,根据对其标准通过能力和使用通过能力及使用通过能力弹性系数的定义,提出基于列车运行图平均最小列车间隔时间的区段标准通过能力和考虑列车运行图缓冲时间的区段使用通过能力的计算方法。通过分析高速铁路区段无越行条件下运行列车组两列车在中间站停车办理作业对区段额外占用时间的影响,并结合有停车作业列车出现的概率,推导列车在中间站停车平均额外占用区段时间的算式,进而得到列车运行图平均最小列车间隔时间的算式;由给出的允许列车后效晚点时长计算得到平均列车运行图缓冲时间。利用算例验证了高速铁路无越行区段通过能力计算方法的可行性和实用性。更多还原

【Abstract】 According to the characteristics of high speed railway section without train overtaking,this paper defines the standard carrying capacity,practical carrying capacity and the elastic coefficient of practical carrying capacity,and proposes the methods for calculating the standard carrying capacity based on the minimum average interval of train diagram as well as the practical carrying capacity considering train diagram buffer time.The influence of the in-service train group(two trains)stopping at the intermediate station for handling operations on the extra occupied time of high speed railway section without train overtaking is analyzed.Combined with the probability of train stopping for handling operations,the formula is deduced for calculating the average extra section occupied time of train stopping at the intermediate station.Then the formula for calculating the average minimum train interval of train diagram is obtained.With the allowable train aftereffect delay time given,the average buffer time of train diagram can be got.Example has validated the feasibility and practicability of the proposed method for calculating the carrying capacity of high speed railway section without train overtaking.更多还原
