摘　　要：国内外主要城市环线大多为连接城市二环、三环的线路,而西安地铁8号线作为线网唯一环线,充当了地下“2.5环”的重要角色,串联西安最多主城区域。8号线建成后将成为国内地铁首条成环运营的无人驾驶智慧环线,因此,其运营组织方案是前期研究的重点和难点。以地铁8号线功能定位和客流特征为基础,对速度目标值、车辆选型及编组、运输组织模式、行车组织方案、运营管理等进行分析研究。全线采用80 km/h速度目标值;按照5人/m 2的站立标准计算列车定员,采用A型车6辆编组;全自动无人驾驶独立运营组织模式,与线网中1、2、3、4号线等18条线路换乘;根据预测客流及网络化需求,内、外环均开行一个大交路,初、近、远期高峰开行对数为22,24,28对/h;全线设置配线8处,满足全自动运行技术要求,并对该类型地铁线路的前期研究思路、运输组织模式、行车组织方案等相关问题提出合理化建议。Most of the ring roads in major cities at home and abroad are connecting the second and third ring roads. As the only loop line in the network, Xi’an Metro Line 8 plays an important role of the underground “2.5 ring road”, connecting the most main city areas in Xi’an. After completion, Line 8 will become the first unmanned intelligent loop line in China, and its operation organization plan is the focus and difficulty of the preliminary research. Based on the function orientation and passenger flow characteristics of Metro Line 8, this paper analyzes and studies the speed target value, vehicle selection and marshalling, transportation organization model, traffic organization scheme, operation management and so on. The speed target value of 80 km/h is adopted for the whole line, and the train seating capacity is calculated according to the standing standard of 5 people/m^(2), and 6 type A cars are grouped. Automatic driverless independent operation organization model is employed and transfer is permitted with 18 lines such as Line 1, 2, 3 and 4 in the line network. According to the predicted passenger flow and network demand, the inner and outer ring roads are open to a large intersection, and the initial, near and far peak traffic are 22, 24 and 28 pairs/h respectively. The whole line is equipped with 8 wiring points to meet the technical requirements of automatic operation. Finally, this paper puts forward some reasonable suggestions on the preliminary research ideas, transportation organization model, traffic organization scheme and other related issues of this type of metro lines.
