宜万铁路东起鸦宜铁路花艳站,西止达万铁路万州站,是铁路进出川渝地区的东通道之一,也是沪汉蓉快速铁路客运通道的重要组成部分。沪汉蓉快速铁路客运通道途经川、渝、鄂、皖、苏、沪6省市,联接长江上、中、下游,是横跨我国东中西部的重要铁路通道。铁路位于鄂西渝东山区,地形非常困难,地质异常复杂。针对路网规划、宜万铁路功能定位、地形地质条件、环水保要求、地方经济发展和施工运营安全等特点,对铁路接轨点、线路走向、复杂地质地段等线路方案的选择进行研究分析,提出复杂山区铁路线路选择的思路和方法,为类似工程项目选线提供参考。
Yichang-Wanzhou Railway starts from Yanhua Station on the east to Yay Wan Railway and Wanzhou Station on the west to the Daban Railway. It is also one of the eastern thoroughfares for railways entering and leaving the Sichuan-Chongqing region and an important part of Shanghai-Harbin Express Railway Passenger Transport Corridor. The Shanghai-Harbin Express Railway Passenger Passage passes through 6 provinces and cities of Sichuan, Chongqing, Hubei, Anhui, Jiangsu and Shanghai and connects the upper, middle and lower reaches of the Yangtze River. It is an important railway passage across the eastern, middle and western parts of China. The railway is located in Dongshan District of West Chongqing and Chongqing. The terrain is very difficult and the geology is extremely complicated. In view of the characteristics of road network planning, functional positioning of Yichang-Wanli Railway, topographic and geological conditions, demands of environmental protection and water conservation, local economic development and construction and operation safety, the paper analyzes the choice of railway schemes such as railroad junction, line direction and complex geological sections, The ideas and methods for selecting complex railway lines in mountainous areas are put forward to provide references for the similar project route selection.
