铁路选线工作是铁路勘测设计中最根本、最重要的一项工作,其好坏不仅影响工程质量和工期,而且影响工程造价和运营效率,影响工农业生产的发展和人民生活的改善。但摸清地形、工程地质,水文情况,重视区域性地质测绘,做好综合选线,又是新建铁路困难山区铁路方案选择成败的关键之一。下面就以邯长线涉县至黎城段困难山区线路方案选择过程为例,来说明加强区域性地质测绘工作,做好综合选线的重要性和必要性。
Railway alignment is the most fundamental and important task in railway survey and design. Its quality not only affects the project quality and construction period, but also affects project cost and operational efficiency, and affects the development of industrial and agricultural production and the improvement of people’s life. However, knowing the topography, engineering geology and hydrology, paying attention to regional geological mapping and doing a good job of integrated route selection is also one of the keys to the success or failure of the rail project in mountainous areas where new railways are difficult to build. Here to Han long line Shexian to Lai Cheng difficult mountain line program selection process as an example to illustrate the strengthening of regional geological mapping work, do a good job of the importance and necessity of a comprehensive route selection.
