以山西中南部通道翻越吕梁山越岭方案为例,从区域地形、地质出发,结合沿线经济据点、煤矿分布、泉域保护区及自然保护区分布,综合经济、技术比选,确定了合理的越岭方案,阐述了越岭选线需要综合考虑各相关因素和条件,才能选择出经济合理的线路走向。铁路越岭选线不仅受到地形、地质条件限制,而且需要合理处理线路走向和地方经济发展、环境保护等全方位的关系,做到综合社会效益最佳。 Taking the south-central Shanxi channel crossing the Lvliang Mountain Crossing Project as an example, based on the regional topography and geology, combined with the economic base along the route, the distribution of coal mines, the distribution of spring reserves and nature reserves, and the comprehensive economic and technical comparison, Ridge program, elaborated on the need to comprehensively consider all relevant factors and conditions in order to select an economical and reasonable route. The selection of railroad lines is not only limited by the topography and geological conditions, but also needs to deal with the full range of the relationship between the line direction, local economic development and environmental protection so as to achieve the best overall social benefits.
