摘要
以瑞梅铁路广东段为依托,针对山区铁路复杂的工程地质条件及不良地质发育的现象,提出了经危岩、落石和崩塌的3条线位方案,经石灰石矿采空区以及岩溶区段的2条线位方案。经现场详细勘察,综合比较分析各线位方案的优缺点,最终选择右侧长隧道大绕避危岩、落石方案以及右侧绕避石灰石矿采空区方案作为该区段线路的贯通方案。本文可为工程地质条件复杂、不良地质现象发育地段的山区铁路地质选线工作提供一定的参考。
Based on the Guangdong section of Ruijin-Meizhou railway,this paper puts forward three line positions through dangerous rock,falling stone and collapse,and two line positions through limestone mine goaf and karst section,aiming at the complicated engineering geological conditions and bad geological phenomena of railway in mountainous areas.After a detailed investigation on the site,the advantages and disadvantages of each line plan are comprehensively compared and analyzed.Finally,the right side long tunnel and the right side long tunnel and the right side long tunnel are selected as the connection plan of this section.This paper can provide some reference for railway geological route selection in mountainous areas where engineering geological conditions are complex and undesirable geological phenomena are developed.
