村镇建筑群火灾蔓延模拟与案例
Fire spread simulations of building groups in rural areas

我国西南村镇地区建筑密集，木结构众多，火灾频发。为有效防范村镇区域火灾，判断和识别其中潜在的火灾风险，该文提出了针对村镇区域建筑群的火灾蔓延模拟方法，并基于OSG （open scene graph）图形引擎开发了可视化平台。采用该方法对贵州温泉村和云南独克宗古城进行火灾蔓延模拟，并完成了火灾蔓延过程的可视化展示。结果表明：火灾蔓延模拟结果与实际情况吻合良好，该文提出的火灾模拟方法能够辅助调查火灾事故原因，并为消防规划和火灾防控提供科学依据和技术支持。
Abstract：Rural areas in southwestern China have high density building environments with mostly wooden structures with many fires in recent years. A fire simulation model was developed for a typical rural design to identify potential fire risks with a visualization platform based on the OSG (open scene graph) graphics engine. Visualizations of simulation results for Wenquan village and Dukezong city agree well with the actual fire hazard. This simulation method can be used to assist fire investigations, as well as to provide a scientific basis and technical support for fire prevention planning and fire control.
