摘 要 京沪高速铁路是投资规模最大、技术含量最高的一项工程,也是我国第一条具有世界先进水平的高速铁路,正线全长约1318公里,与既有京沪铁路的走向大体并行,全线为新建双线,设计时速350公里,初期运营时速300公里,共设置个客运车站。该项工程预5年左右完成,2010年投入运营。京沪高速铁路建成后,与既有京沪铁路实现客货分流。新建的高速铁路为客运专线,既有的京沪铁路为货运主线。届时,北京至上海高速列车全程运行时间只需5小 时,比目前京沪间特快列车缩短9小时左右,年输送旅客单方向可达8000余万人,大大释放既有京沪铁路的能力,使既有京沪线单向年货运能力达1.3亿吨以 上,使其成为大能力货运通道,从而满足京沪通道客货运输需求,从根本上解决京沪通道运输能力紧张的状况,真正实现“人便其行、货畅其流”。 ABSTRACT Beijng-Shanghai High-Speed Rail Passenger Line is the largest and the highest technological content of a project, but also Chinas first world-class high-speed railway. The whole line of it is about 1318 kilometers, with the existing Beijing-Shanghai railway parallel to the general, across the board for the new two-lane, the design speed 350kilometers, the initial period operation speed 300 kilometers, altogether establishes 24 passenger stations. After the completion of the Beijing-Shanghai high-speed railway, with already has the Beijing to Shanghai railroad realization passengers and cargo to diverge. By then, the Beijing-Shanghai high-speed train running the whole time just five hours, than at present between the Beijing-Shanghai express train about nine hours shorter, in a one-way passenger transport up to 8,000 million, a significant release of both the capacity of the Beijing-Shanghai Railway, so that the existing Beijing-Shanghai line of one-way cargo capacity was 130 million tons more than the ability to become a major freight routes, the Beijing-Shanghai route to meet passenger and freight transport demand, a fundamental solution to the Beijing-Shanghai-channel transport capacity of the state of tension, real people by their deeds, smooth flow of goods. This in the domestic construction milestone, technical standards, the highest standards of green - green-wide passenger—Beijng-Shanghai High-Speed Rail Passenger Line . The import mileage of Zhangxia tunnel is DK427+980, export mileage isDK428 +672, and the total length of this tunnel is 672 meters. This tunnel pass through low-relief terrain. T
