Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The present invention provides a method for demonstration and early warning of dam break flood based on BIM technology, such as figure 1 As shown, based on BIM technology, software platforms such as 3ds max, Realflow, Rayfire, and GIS are integrated to build a final dam failure flood risk early warning platform. After the 3ds max software combines Rayfire and other plug-in platforms to complete the 3D real terrain model and the damage model of the dam building, the entire model is imported into the Realflow software for the actual data of the dam failure and the evolution of the flood to generate the final animation of the flood evolution. In the later stage, NUKE, Pr and other tools were used to beautify the animation demonstration process, making the demonstration process intuitive. Specifically follow the steps below:

Abstract

The invention discloses a method for demonstration and early warning of dam break flood based on BIM technology, specifically: first establish a three-dimensional solid terrain model and a building model; then calculate the parameters of the dam break development process and the dam break flood parameters, and establish the dam break The 3D simulation model; combine the obtained 3D solid terrain model and building model, the 3D simulation model of dam failure with the particle fluid system to realize the real simulation of the dam failure process and flood evolution; finally, animation and rendering of the simulation process, Get 3D real dam break flood evolution animation. The invention also discloses a demonstration early warning platform based on the method. The method of the invention can simulate the dam break process and flood submersion range, and intuitively understand the evacuation of residents and the submersion status of important buildings when facing a dam break by using animation. In order to obtain the simulated flood submersion process after the dam break, provide risk analysis and technical assessment data for water conservancy project construction, design and construction units.

Description

technical field [0001] The invention belongs to the technical field of earth-rock dam break flood risk assessment technology, and relates to a demonstration and early warning method for dam break flood based on BIM technology, and also relates to a platform based on the above demonstration and early warning method. Background technique [0002] BIM (Building Information Modeling) is based on the relevant information data of construction projects, simulates the real information of buildings through digital information simulation, and realizes project supervision, property management and equipment management through three-dimensional building models. , digital processing, engineering management and other functions. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. For the water conservancy industry, large water conservancy design institutes have begun to...
