摘　　要：提出了古村落消防管网安全度评估方法,根据结构可靠度理念,以EPANET喷嘴功能评估的管网消防供水能力为抗力,以ISO法评估的消防需水量为效应,将两者之比定义为安全度指标。把所提方法应用于云南某古村落实际消防供水管网,结果表明,该古村落消防供水安全度普遍偏低;简单依据人口规模来设计消防供水系统无法满足其实际消防用水需求;木结构和木瓦屋顶的大量使用导致古村落建筑消防供水安全度方面存在显著问题,可通过替换部分木结构墙面为耐火等级高的防火砖、屋顶采用改进型耐火瓦片铺设等措施提高其消防供水安全度,最高可提升至原水平的240%。A safety assessment method for the fire pipe network of ancient villages is proposed.Based on the concept of structural reliability,the fire water supply capacity of the pipe network,assessed using the EPANET nozzle function,is taken as the resistance,while the fire water demand,evaluated by the ISO method,is considered the effect.The ratio of the two is defined as the safety index.This method is applied to the actual fire water supply network in an ancient village in Yunnan Province.The results show that the safety of fire water supply in the village is generally low.Designing a fire water supply system solely based on the population size is insufficient to meet actual fire water demands.The widespread use of wood structures and shingle roofs in the village exacerbates fire water supply safety issues.These can be addressed by replacing some wooden structural walls with fire-resistant bricks and upgrading the roof with fire-resistant tiles,which can increase fire water supply safety by up to 240%compared to the original level.
