Abstract Research purposes: The accuracy of railway survey is restricted by the influence of terrain, climate and complex geological conditions in difficult and dangerous mountainous areas in the western China. The previous research is only a simple combination of sky and earth technology, and the comprehensive application of the method is not discussed enough. Based on the key problems and actual needs of railway survey in western mountainous areas, this research puts forward a four-dimensional survey system integrating the identification of geological body's temporal and spatial evolution process, to provide reference for scientific research and survey work in the field of railway survey in western mountainous areas.
Research conclusions: (1) A set of four-dimensional survey system of "space-sky-ground-well" is constructed, which promotes the traditional current survey to the survey of geological body catastrophe evolution. (2) The technical combination principle of "space-sky-ground-well" under different geological problems is described in detail. (3) The "space-sky-ground-well" integrated survey technology will greatly improve the survey accuracy of lithology, structure, geological hazards and deep geological characteristics in western mountainous areas. This technology will be widely used in railway survey in complex and dangerous mountainous areas.

Key words： difficult mountainous areas space-sky-ground-well four-dimensional investigation system
