摘要
研究目的:由广东省单独投资建设并负责运营管理的珠江三角洲地区城际轨道交通网,运行车辆选用与地铁A型车外形尺寸相同的城际动车组,但运行速度大大高于一般地铁,现行有关轨道交通方面的设计规范均不能完全适用于珠三角城际轨道交通项目。为了使工程设计既能实现运营速度目标,保证运营安全,又尽量节省工程投资,因此需要对珠三角城际轨道交通正线线间距进行研究确定。研究结论:珠三角城际轨道交通正线直线地段最小线间距可按下列标准采用:设计速度为140km/h及以下时采用3.8m,160km/h时采用4.0m,200km/h时采用4.2m。曲线两端直线地段的线间距为3.8m时,曲线地段应加宽线间距;曲线两端直线地段的线间距≥4m时,曲线地段线间距可不再加宽。
Research purposes： As the same outline dimension EMU as the A type metro＇s vehicle will be used for the intercity rail transit network in the Pearl River Delta Zone region, with much higher running speed than the metro, the current design specifications for urban rail transit can not fully be applicable to the intercity rail transit in the Pearl River Delta Zone. In order to achieve the design goals of high speed, high security and saving the investment, it is necessary to study and determine the midway between tracks of main line of intercity rail transit in the Pearl River Delta Zone. Research conclusions：The minimum midways between tracks of the main line in the Pearl River Delta Zone Intercity Rail Line can be as follows：In the straight sections, the midway between tracks is 3.8 m when the design speed is 140 km/h and below, the midway between tracks is 4.0 m when the design speed is 160 km/h and the midway between tracks is 4.2 m when the design speed is 200 km/h. In curve sections, the midway between tracks should be broadened if the midway between tracks in straight section on both ends unnecessary to be broadened if the midway between tracks in of the curve is 3.8 m, and the midway between tracks is straight section on both ends of curve is 4 m and above.
