Abstract Research purposes: The terrain and geological conditions of the Wuling Mountains, which extended across western Hunan, western Hubei, eastern Chongqing, and eastern Guizhou, were complex and had a special geographical, geological, and climatic background. With the advancement of the national strategy of western development, the construction of railways in this region had made significant progress and was continuously advancing. This paper summarized the experience of railway engineering in the Wuling Mountain area, and discussed the future development direction.
Research conclusions: (1) The majority of the Wuling Mountain area was located in carbonate plateaus, with a soluble rock area accounting for over 60% of the regional area. Karst was strongly developed, and karst and karst water had become the main geological issues controlling railway line schemes. (2) The morphology, scale, and intensity of karst development in this region were mainly controlled by structures, and overall were characterized by large scale, deep depth, and poor regularity. (3) The local area should followed the concept of "disaster reduction and prevention" for geological route selection. During the survey, a special karst survey should be carried out to investigate the distribution of karst along the route, and "avoidance" should be the first principle for route selection; when it was impossible to avoid, the line positioning plan should be determined according to the principle of "raise the elevation". (4) Utilizing modern information technology, developing new technological equipment, and moving towards more precise identification, reliable analysis, and precise treatment had become an inevitable requirement and trend for controlling karst geological risks and solving engineering problems in the local area. (5) The research results can provide reference for future railway survey, design, and construction in the Wuling Mountain area.
