3 D visualization of geoinformation in slope engineering and its application to the permanent shiplock slope in the Three Gorges Project

Geoinformation of slope engineering mainly contains rockmass structure and its physical property. 3 D visualization of these informations is a key to establish the model of engineering geological structure. In this paper, different symbols and their combination are used to generalize these geoinformations, and 3 D visualization model of the geological structure is established with the relevant fitting function, which can display successfully geological sections and sterogeological blocks at any different locations. Finally, the presented 3 D model is applied to the permanent slope engineering in the Three Gorges project.
