摘　　要：城市轨道交通车站的两端多为曲线,受曲线控制,折返线距离站台较远导致折返能力较低,不能满足行车组织要求。为解决站前直线段长度不足以设置折返渡线的问题,提出一种结合站前区间线间距设置单渡线或交叉渡线进行折返的方案。通过对不同线路偏角、不同道岔型号、不同车辆编组的站前单渡线计算,结合单股道技术作业流程,站前单渡线折返能力可达13~20对/h;通过对不同道岔型号、不同车辆编组、不同车站区段线间距的站前交叉渡线线路计算,结合双股道技术作业流程,站前交叉渡线折返能力可以达到19~25对/h;对于直线电机地铁及其他采用短编组的中低运量系统,折返能力将进一步提高。The two ends of urban rail transit stations are often curved,the turn-back line controlled by the curve is far from the platform,and the turn-back capacity is low,which cannot meet the requirements of the train organization.In order to solve the problem that the length of the straight section in front of the station is insufficient to set up the turn-back crossover line,a scheme was proposed to set up a single crossover line or a scissors crossover line for turn-back in combination with the line spacing in front of the station.Through the calculation of the single crossover line in front of the station with different line angles,different turnout models and different vehicle formations,combined with the technical operation process of the single track,the turnback capacity of the single crossover line in front of the station can reach 13~20 pair/h;By calculating scissors crossover line in front of the station with different turnout models,different vehicle formations,and different station line spacing,combined with the technical operation process of the double track,the turn-back of the scissors crossover line in front of the station can achieve a capacity of 19~25 pair/h.For linear motor metro and other medium and low capacity systems using short vehicle formations,the turn-back capacity will be further improved.
