南北筑通途--写在兰渝铁路全线通车之际

2017-09-29 14:17:52   

兰渝为同类地质的国内外公路、铁路隧道施工提供了方案、贡献了智慧,目前在建的多条地质条件类似的铁路和公路项目,在设计、施工时都向兰渝“取经”,少走了弯路,降低了成本。

黄金通道连接“一带”“一路” 构建西部发展“新动脉”

位于甘肃省定西市岷县的分水岭上,代表长江流域和黄河流域的两块石头,显示出两个不同的区域。脚下,兰渝铁路穿过,正把此前的分割变成紧密的联系。这条钢铁大动脉,在崇山峻岭间穿行,一头是西北黄土高原上黄河穿城而过的兰州,另一头是大西南长江畔的重庆。

兰渝铁路全线开通运营后,我国西部的交通格局也将发生质变。此前,西北与西南的铁路客货交流主要经由陇海线、西康线、襄渝线运输,呈“之”字形布局,线路迂回绕行,导致运输能力紧张,不能满足大区间客货快捷运输需求。

而作为西北、西南地区之间最便捷的快速铁路通道,兰渝铁路全年运输送能力可达6000万吨,可通行双层集装箱货运专列。全线通车后,随着不断提速,兰州至成都、重庆的铁路运费有望降低约三分之一,而时间缩短约三分之二。

铁路全线通车之前,市场已经闻风而动、寻觅商机。

煤炭资源空间分布不均、运力不足是多年来困扰我国能源市场的重大问题,而这一历史近期有望随着兰渝铁路的全线通车而改写:一个规划年产值120亿元、辐射南方地区的新疆煤炭商务中心正随兰渝快车南下,重构南方能源市场。新疆煤交所副总经理张奎认为,兰渝铁路的开通将彻底打破新疆与南方地区能源交通障碍,“疆煤在西南市场占比一直保持在10%左右份额,兰渝铁路通车后,运距减少,运费降低,疆煤南下将成为常态”。

兰渝铁路开通当天,兰州国际港务区组织的两列货运班列,首次截弯取直,沿兰渝铁路直下重庆。一列车上是1500吨铝锭,另一列上是西北的农产品马铃薯和洋葱。而在不远的将来,这些大西北货物将沿着这条线路快速南下,经过重庆、贵州至广西,甚至远销东南亚。兰州和它身后的大西北,将打开它的“南向通道”。

8月底,重庆、广西、贵州、甘肃四省市区签署《关于合作共建中新互联互通项目南向通道的框架协议》。此前,西部地区大多都是东西向大通道,“南向通道”由北部湾海港和南宁向北经贵阳、重庆、成都,连通兰州和西安,将形成我国西部地区的第一条南北向的纵向大动脉,也使我国西北地区多了一条向南出海的大通道。

经过测算,如果从兰州经过兰渝铁路向南到新加坡,比向东出海时间节约5天左右,陆海运距缩短约一半。借着兰渝铁路这条在中国西北和西南之间最近的连线,“一带”与“一路”将无缝衔接。

随着兰渝铁路穿过千山万水、全线通车,我国西部崛起一条纵贯南北的大通道,西南则与西北实现资源、产业优势有效互补。西部开发开放必将澎湃新的脉动!(记者王丁、任卫东、屠国玺、王衡、张翅、韩振)
