摘要
为满足流域防洪可视化仿真需求,提出了适用于不同尺度下防洪要素表达及其性能优化的关键技术。研究了如何构建大范围的轻量化三维仿真场景,针对宏观、中观、微观多尺度下的不同水系关键要素,提出相应的表达方式与性能优化技术思路,如宏观下流域海量水系矢量表达内存优化技术,中微观场景下集成一维与二维水文水动力学模型成果的仿真技术,探索了虚拟仿真VR设备与防洪场景的同步联动。通过以上方式实现流域场景下防洪成果的一体化仿真呈现,有助于在防洪工作中快速获得准确直观的决策辅助信息。
In order to meet the simulation requirements for flood control within a watershed,key technologies applicable to how to express flood control elements at different levels have been proposed.We analyzed how to construct a lightweight 3D simulation scene for a large-scale watershed level.We propose different representations and technical ideas for key elements of the water system at multiple scales,including macro,meso and micro,such as memory optimization technology for vector expression of massive water systems in watersheds at the macro level,simulation technology for integrating one-dimensional and two-dimensional hydrological and hydrodynamic model results in meso and micro scenarios.We explored further synchronous linkage of flood control scenarios using virtual simulation VR devices.By combining the above methods,the presentation of integrated simulation of flood control results in watershed scenarios were realized.The research results were helpful to obtain accurate and intuitive decision aid information quickly in flood control work.
