The world advanced modeling technology for 3D geological curved surface is introduced and the method advantage is analyzed as well. This method is introduced to the modeling of the complicated geological mass. The flow modeling tools are developed in combination of the engineering geological flow and habits. The successful application of the technology in Batang Hydropower Project proves that DSI method is applicable to the 3D modeling of the discontinuous, nonlinear and dualistic structural geological mass. In Combination with the engineering geological database, the work efficiency is improved by application of the flow tools to establish the 3D model of the complicated geological mass. The work process displays the recognization of geologist to the geological mass. The modeling accomplishment reflects the spatial rela- tionship of the geological objects.
