摘要

研究区域中国湖北省山洪易发区（大同、张邦、石子镇）研究重点本研究以湖北省山洪受灾严重的山区为研究对象。以其中三个地区为例，提出了一种基于三维数字孪生场景的洪水模拟方法。该方法可以三维动态显示洪水淹没范围、水位上升过程和淹没深度。在此基础上，通过构建数字山洪模拟平台，实现基于三维交互场景的山洪灾害模拟，并根据模拟结果自动识别危险区域和疏散路线。通过三维场景的洪水演绎，确定三区不同条件下危险区域的户数分别为46175户和51户，共制定了9个临时安置点，共建立了9条疏散路线。本文在技术理论上创新地将三维洪水实时演绎与洪水风险模拟相结合。这一创新为防洪减灾提供了强有力的支持，使洪水模拟能够通过三维交互对防洪方案进行预览和预测。

High speed flash flood deduction and prevention method based on three-dimensional digital twin scene

Study region

Flash flood prone areas in Hubei, China (Datong, Zhangbang, and Shizi Town)

Study focus

This study focuses on the mountainous areas in Hubei Province that are severely affected by flash floods. Taking three of these areas as examples, a flood simulation method based on a three-dimensional digital twin scene is proposed. This method can dynamically display the flood inundation range, water level rise process, and inundation depth in three dimensions. On this basis, by constructing a digital flash flood simulation platform, flash flood disaster simulation based on a three-dimensional interactive scene is realized, and based on the simulation results, the danger zone and evacuation route are automatically identified.

New hydrological insights for the region

Through the flood deduction in the three-dimensional scene, the number of households in the dangerous area under different conditions in the three areas is determined to be 46,175 and 51, and a total of 9 temporary resettlement points are formulated, and a total of 9 evacuation routes are established. This paper innovatively combines three-dimensional flood real-time deduction with flood risk simulation in technical theory. This innovation provides strong support for flood control and disaster reduction, making it possible for flood simulation to preview and predict the flood prevention plan through three-dimensional interaction.
