摘要
宜昌至涪陵高速铁路位于湖北省西部、重庆市中东部,设计速度为350 km/h,是沿江高速铁路通道的主干线路。沿线地形、地质条件复杂,溶洞、暗河发育,遵循“先绕避、短通过、抬高程、傍河边、靠既隧、人字坡”的选线原则,首先对既有宜万铁路隧道涌水以及病害较多的野三关至建始段进行了深入研究,其次结合沿线经济据点分布、城市规划、长江、清江桥位、沿线地形地貌、不良地质条件、环境敏感区分布、工程投资等多方面因素,对恩施至涪陵线路走向方案进行充分比选,最终采用区域路网布局合理、兼顾经济据点较多、吸引客流能力较好、地形地质条件相对较好、线路顺直、工程投资较省的经五峰、鹤峰北方案。
Yichang-Fuling High-speed Railway is located in the west of Hubei Province and the middle east of Chongqing City,with a design speed of 350 km/h,and is the trunk line of the high-speed railway channel along the Yangtze River.The geological conditions along the line are complex.Karst caves and underground rivers are developed.Following the route selection principle of“avoiding first,passing short,raising elevation,being close to the river,relying on existing tunnels and herringbone slopes”,the existing Yiwan Railway tunnel water gushing and the Yesanguan-Jianshi Section with many diseases were first studied in depth,and then combined with the distribution of economic strongholds along the line,urban planning,the Yangtze River and Qingjiang River bridge sites,the landform along the line,adverse geological conditions,the distribution of environmentally sensitive areas,project investment and other factors,the route scheme of Enshi-Fuling Railway is fully compared and selected,and the scheme passing through Wufeng and Hefeng North with reasonable regional road network layout,more economic strongholds,better passenger flow attraction,relatively good topographic and geological conditions,smooth route and less project investment is finally adopted.
