Paper Abstract

It is important to unify the model of geological structures with subsurface engineering structures in digital underground space (DUS). This paper puts forward a 3D model, feature constraints based (FCB) for DUS, which integrates the model of these two objects in the point of 3D continuous field of underground space. The FCB model describes spatial objects in DUS as composition of their features which is modeled from various constraints. A trial modeling system, ExpoDUS, developed with MS VC++ 6.0, MS Access and OpenGL, proves the feasibility of this model and demonstrates spatial query and analysis using actual data obtained from a key project of electric substation special for Shanghai Expo 2008 in China. Although designed to meet the requirements of underground engineering, our methodology could also be applied in superstructure modeling.
