桂西北少数民族木构民居绿色更新中的防火问题研究

The project aims at studying on fire protection in green renewal of minorities traditional wooden buildings (also called suspended wooden building) in northwest of Guangxi. There are more mountain area and less flat ground in Northwest of Guangxi. The local villagers dwell together along the mountain slop. Wooden constructions are built densely and combustible. The regulations of fire protection and technology of city do not apply to the houses of this area. Serious fires always happen, which always burn all the wooden structures locating together. Fire disaster is a primary reason which leads to poverty of local villagers. Fire has been the key problem to be solved in Northwestern of Guangxi. It does research on green fire protection systems and technologies, which is suitable for minority villages in Northwest of Guangxi, Basing on retaining local traditions and ethnic minority mode technology of traditional houses and following both the green design concept and layout characteristics for intensive timber-framed houses.The research achievements will provide not only adaptive fire technology for green renewal of minorities suspended wooden buildings in northwest of Guangxi, but also have great application value for all the wooden architectures. And it also has important practical significance to accelerate the steps of villagers from poverty to richness.

项目旨在研究桂西北少数民族木构民居（又称吊脚楼）绿色更新中的防火问题。桂西北山多地少，当地村民依山沿坡聚集而居，吊脚楼密集易燃，城市的防火规范和防火技术受环境限制而难于实施，“火烧连营”的重大火灾频发，当地因火灾致贫返贫现象严重，防火问题一直是桂西北地区亟待解决的科学问题。项目在保留当地传统少数民族聚居模式和民居传统建构技术的基础上，遵循绿色的设计理念，针对木构民居的密集布局特点，研究适合桂西北少数民族聚居村寨的绿色防火体系和技术，研究成果不仅为桂西北少数民族吊脚楼的绿色更新提供适应性的防火技术，对木构建筑防火亦具有推广应用价值，对加快广西少数民族地区脱贫致富的步伐具有重要的现实意义！

结题摘要. 项目研究桂西北少数民族木构民居（又称吊脚楼）绿色更新中的防火问题。桂西北山多地少，当地村民依山沿坡聚集而居，吊脚楼密集易燃，城市的防火规范和防火技术受环境限制而难于实施，“火烧连营”的重大火灾频发，当地因火灾致贫返贫现象严重，防火问题一直是桂西北地区亟待解决的科学问题。项目在保留当地传统少数民族聚居模式和民居传统建构技术的基础上，遵循绿色的设计理念，针对木构民居的密集布局特点，研究适合桂西北少数民族聚居村寨的绿色防火体系和技术。. 本项目研究达到预期目标，取得了3项重要研究成果：一是提出杉木吊脚楼的“水雾防火墙”设计及其验证方法；二是提出杉木吊脚楼的“重型木骨架”设计方法，三是杉木吊脚楼最小安全防火间距数值模拟研究方法。项目完成研究论文8篇，其中已发表研究论文5篇，北大核心期刊3篇；申请中国发明专利2项，均已进入实审阶段；培养了3名青年教师和8名硕士研究生，建立了木构建筑虚拟仿真实验室，在此基础上成功申报了省部级绿色建筑虚拟仿真实验教学示范中心。. 研究成果不仅为桂西北少数民族吊脚楼的绿色更新提供适应性的防火安全技术，对木构建筑防火亦具有推广应用价值，对加快广西少数民族地区脱贫致富的步伐具有重要的现实意义！
