Abstract

Research purposes: According to the problems in the geological alignment of mountain railway，such as the complex geological conditions，many alignment schemes，long period of demonstrating scheme and hard decision － making，the study was done on the3D visualization technology for railway geological alignment and GIS evaluation method for engineering geological condition to realize the modularization，quantification and systematization of geological alignment and evaluation method．

Research conclusions: Through the studies on multi － source geological information integration， remote sensing information sampling，3D geography modeling and engineering geological evaluation method，the 3D visualization GIS integrated system was established to realize the functions of geological information management，spatial analysis， thematic mapping and 3D view，and improve the efficiency and reliability of railway geological alignment in mountain area．

Key words
