高层建筑火灾网络模拟

NETWORK SIMULATION OF HIGH-RISE BUILDING FIRE

高层建筑防灭火以及人员疏散的正确决策,关键在于对灾变条件下高层建筑中风流参数变化的正确预测,特别是在采取一定的风流控制措施之后各通道内风量、风向、烟流蔓延范围、烟气浓度变化等参数的预测。论文全面地介绍了全风网网络模拟软件HRBFS的基本原理、组成部分、软件特点、系统的结构以及需要输入的数据等。模拟软件可以有效地校验消防四大系统的设计和运行,并能为消防决策和建筑火灾事故分析提供有力的依据。

The right decision of fire prevention and suppression, personnel evacuation in high-rise building fire depends on right forecast of the veriations smoke parameters in a building, especially parameters such as （airflow quantity and direction, smoke spread area and smoke concentration） in corridors at an early stage and after smoke istics control measures leeing taken. The paper introduces the basic theory, component, character, framework and necessary data of the HRBFS. Simulator, a powerful tool for design, verification of fire system, decision-making and fire accident analysis.
