Abstract:Research purposes: Guizhou-Guangxi Railway locates in mountain area of Southwestern China and crosses Guizhou province and Guangxi autonomous region. The topography and geology along the line are very complicated and seriously affects the route selection. Therefore, it is necessary to survey geological conditions widely in the region for route selection on primary survey stage for reconstruction of Guizhou-Guangxi Railway in order to save project cost, reduce geological disasters and work hazards, and eliminate potential troubles in operation.
Research methods: On the basis of collecting geological information in the region the route selection program was decided from point of geological view through making systematical exploration by means of geological survey, boring and static penetration tests to find out serious problems related to engineering geology.
Research results: Through making comparison of geological conditions in different route selection programs, finally the route selection program with better geological conditions was decided.
Research Conclusions: The topography and geological conditions are very complicated in Southwestern China, so the full investigation of geological conditions along the line should be made so as to avoid complicated and seriously unfavorable geological section in course of route selection. The systematical introduction is given to several typical examples of route selection based on geological conditions on the primary survey stage for reconstruction of Guizhou-Guangxi Railway, and the brief discussion is made on avoiding serious geological trouble in course of route selection. The thoughts, comparison conditions and evaluation opinions introduced in this paper route selection can be used for reference to the survey and design of other mountain railways.
