Abstract:Research purposes: Taking geographic information system technology, engineering geology, computer 3D analysis technology, database technology and national digitalmap as the carrier and GIS geographic information system as technicalplatform, the large -scale network engineeringSQLServerdatabase isbuilt tomanage the large numbers of scattered and cluttered geologicaldata, so through the database, these data can be processed into a "digital" information which can be repeatedly used and permanentpreservedwith high efficiency.
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.
