Abstract
Railway location is the foundation work for comprehensive railway design, which requires overall planning, all-round consideration, sound adaptation to local conditions and reasonable choices because of its broad involvement. Across Hunan, Guangxi and Guangdong provinces, Luoyang-Zhanjiang Railway passes through diverse geomorphic units such as low mountains and hills, karst isolated peaks and plains. Adverse geological conditions and special rock and soil are widely distributed along the line. In this paper, by studying the minimum curve radius, maximum grade, reasonable plan and profile standards applicable to the topographic and geologic conditions along the line, the author carried out a wide range of comparison of locations over mountain in the reservoir area which achieved good route selection effects, proposed essential principles of route selection according to the characteristics of the karst regions, and made a successful trial on how to improve engineering geologic location of line in landslide area, which provided valuable experience and lesson for railway location in such topographic and geological conditions.关键词
