Abstract：Abstract ： Research purposes ： Based on years of railway route selection practices in complicated mountainous areas of
nortliwest China，the characteristics of railway route selection factors in complicated mountainous areas are summarized
and analyzed. The research presents the Methods and ideas of railway route selection in complicated mountainous areas，
the railway route schemes are determined scientifically and reasonably. The research provides technical guidance for the
railway route selection in domestic complicated mountainous areas and lays the technical foundation for Chinese railway
technology to go overseas.
Research conclusion ：( 1)The five most obvious features of railway in complicated mountainous areas are" sparse urban
economic areas， difficult topography， complicated geology， high environmental sensitivity and strong requirement of engineering safety". (2) The methods and ideas of railway route selection in complicated mountainous areas should implement "planning，major projects，environmental protection，geology，safety，comprehensive and systematic selection". (3) The impacts of the main effect factors on railway route selection should be fully analyzed. The principle of route
selection and engineering treatment measures should be specifically proposed，comprehensive comparison and analysis is
according to the principle of 11 make minor sacrifices to safeguard major interests"， then the optimal solution shall be
determined. (4) The development of relevant professional technology，railway survey geographic information technology，
construction technology and equipment level should be followed upcontinuously. Technological innovation should be carried out actively, in order to open thoughts and ideas of the railway route selection. (5) Methods and ideas of railway route selection in complicated mountainous areas, which were pointed out in this research, have an important reference and guidance significance for the domestic and international railway route selection in complicated mountainous areas.
