摘　　要：为预测顶部开口腔室池火的燃烧速率,基于火灾动力学理论构建了顶部开口腔室池火燃烧速率预测半经验模型,利用实验数据的多元回归分析计算模型参数。模型燃烧速率的计算值与实际测量值的对比结果表明,燃烧速率预测模型对实际火灾场景模拟的可信度较高,研究成果可为船舶、地下建筑等顶部开口腔室的安全设计、火灾预防和火灾扑救等提供参考。In order to predict the burning rate in a ceiling vented compartment,a burning rate semi-empirical prediction model used in pool fire in a ceiling vented compartment was set up based on fire dynamic theory.Based on experiment data,the model parame-ters were calculated by multiple regression analysis.The compari-son results between the calculated value and the measured value of burning rate showed that the prediction model was reliable and use-ful in practice.The paper can give reference for fire protection de-sign and fire prevention and also fire fighting in a ceiling vented compartment.
