Research conclusions:Through the study, the problems related to the informationmanagementforengineering geological survey data are solved, and the integrated management and multi -bearings inquiry and application of the survey achievementare realized. The practice has proved thatGIS -based railway engineering geological survey database can realizemanagementof the data in orderwith high efficien.t This is good trial for increasing the production efficiency,improving the survey quality and the basic geographic information system and pushing forward the application ofGIS in railway engineering geology.
