The geological background of a proposed railway is unique and the engineering geology and hydrogeology conditions are complex.It is necessary to identify the main engineering geological problems,carry out comprehensive research on route selection based on the concept of disaster reduction,and take engineering measures to avoid disaster risks.The results show that karst and karst water system,environmental hydrological conditions,unloading geological hazards,shale gas generation and storage in Qingyu Hejian block control the selection of railway passage schemes.The karst system of Qingyu Hejian block was subdivided into 5 big areas and 21 small areas by special research.The population distribution and available water resources were classified and the unloading geological hazards and shale gas development laws and their impact were evaluated.Through comprehensive comparison and selection of multiple schemes,the passable schemes are found out,and the scheme research suggestions are put forward considering the construction organization,environment,hydrology and ecological guarantee,engineering construction operation risk and other factors.
