Through the analysis of current related research on geological three-dimensional modeling and simulation analysis in different areas of underground space,by using the latest research results of 3D GIS,and on the basis of the characteristic and application of salty rock,a geological 3D model and analysis application platform of salty rock is constructed. Key technologies and methods in the platform are researched and realized. After the functional structure of the platform is designed in detail,the organization and management of 2D and 3D spatial data of salty rock are carried out by the means of Geodatabase models. Based on the comprehensive utilization of these spatial data,with the help of object oriented programming,key technologies of the platform are realized,such as the construction and spatial analysis method of 3D models of salt stratum based on subdivision virtual drills,threedimensional topological surface reconstruction technology based on Sonar Cavity data of salty cavity,construction method of 3D voxel models of salty cavity wall rock based on 3D GIS spatial analysis,and the direct volume rendering technology of irregular data field of salt rock. The research results can provide powerful technical support and scientific basis for reasonable exploitation and utilization of underground salt rock cavern.
