3D Geological Modeling and Dynamic Simulation Analysis to Complex Underground Structure Groups

This paper put forward a dynamic simulation approach for the whole construction process of the underground structure group,based on the3D engineering-geological modeling technique and the dynamic simulation technique.The approach simulates and analyses the construction of the underground engineering by taking into account of a variety of geologic factors before a 3D geological model of the underground structure group is fully built up. Then by integrating the computation with the 3D model,the dynamic visualization of the simulation results is realized under the actual geological conditions. An example of application demonstrates the feasibility of the approach.The proposed approach provides a convenient and visually intuitive means for the analysis in the construction management and decision-making of large-scale underground structure groups.
