AUTOMATIC MODELING AND COUPLING OF GEOLOGICAL AND ENGINEERING OBJECTS BASED ON TP VOLUME

The current three-dimensional geological simulation technology only deals with modeling of purely geological objects and does not take into account the mutual coupling relationship between geological and engineering entities, which has limited the veracity and availability of computer simulation and cannot meet the requirements of three-dimensional design and analysis in geological engineering. The modeling and coupling of three-dimensional geological and engineering objects is prerequisite for complete analysis of three-dimensional geological engineering. Oriented at the problems of the existing three-dimensional geological models and modeling methods, a new automatic unification modeling method coupling geological and engineering entities is systematically studied and proposed which characterizes not only single geological or engineering objects, but the factual relationship between them as well. The method uses TP (Triangular Prism) volume featured by simplicity and efficiency as the unification modeling primitive. The three-dimensional geological TP model is constructed on the basis of deviated borehole correction, and the appropriate engineering model is constructed by sequential section modeling approach. For the aim and demand of unification modeling, the TP reconstruction approach is achieved to accomplish the effective subdivision and restructuring of TP under the condition of complex sections. The experiment shows that the proposed method could build the three-dimensional seamless unified model of geological and engineering entities automatically and efficiently.
