黄百铁路选线设计体会

Route Selection Design of Huangtong-Baise Railway

黄百铁路位于黔西南及桂西北之间云贵高原边缘与广西盆地的过渡区—斜坡地段,沿线地形、地质条件极为复杂,尤其是镇宁、紫云、乐业周边岩溶强烈发育,全线风景名胜区、自然保护区、水源保护区等控制因素较多,线路经过的主要经济据点呈"之"型分布,位于省界处的红水河桥位方案是控制线路走向的重要因素。文中就以上特点主要介绍了可研阶段线路选线设计中的一些体会。

Huangtong-Baise Railway is located in the transition area-slope section between Yunnan-Guizhou Plateau edge and Guangxi Basin. Topographical and geological conditions along the line are extremely complicated, especially for are- as around Zhenning County, Ziyun County and Leye County, where Karst is developed strongly, and there are many control factors on the whole line, such as Scenic Spots, Natural Reserve Zones and Water Source Conservation Areas. Main economical zones along the railway are distributed as Zigzag shape. The location of Hongshuihe Bridge located in the provincial boundaries area is key factor for the strike of alignment. This paper introduces some understandings in the route selection design in feasibility study stage based on the above features.
