Theoretical framework of visualization-based disaster digital simulation

Visualization-Based Disaster Digital Simulation Reconstruction Theory is the best solution to solve the fatalness and non-repeatability of disaster experiment. The paper presents the concept, technical support, feasibility and content of Visualization-Based Disaster Digital Simulation Reconstruction Theory. The operation flow of disaster digital simulation theory, and the principles and procedure of establishing disaster digital model are proposed. The conceptual paradigm of disaster digital simulation model is built by analyzing the action mechanism and function process between hazard factor and hazard bearing body, together with structural change of hazard bearing body. The work above forms the important part of the whole theoretical system of Visualization-Based Disaster Digital Simulation Reconstruction Theory, which sets solid foundation for visualization platform.
