兰新线兰武段增建二线最大坡度的选择

Added-Building a Second Track Maximum Slope's Selecting of Lanwu Route in Lanxin Railway

从兰武线既有现状出发,针对海拔高、坡度大、列车运行速度低、运输成本高、市场竞争力不足等问题,就实现运输能力和运输质量的同步提高,满足旅客列车提速的需要,提高点线协调能力等方面,对各种限制坡度方案特点进行了详尽地分析、研究和论证.其研究分析方法具有针对性和适用性,对山区铁路的最大坡度选择有借鉴和指导意义.

The article begin with the present situation of Lanwu railway. As a high altitude、a slow speed of passenger train and less compete in market,it is necessary to have a system analysis、investigation and improvement to increase the capability of transportation and quality at same time,to satisfy speed-improving of passenger train,to improve coordination.The analysis method is adaptive and pointed.It is important to help selecting maximum slope in mounta area.
