【摘要】 根据某高能同步辐射光源项目建筑的工艺要求和空间特点,分析其办公用品、电缆等主要火灾荷载,针对设计方案中的防火设计难点,从防火分隔、灭火系统、排烟系统、电气系统等方面提出初步解决方案。利用消防安全工程学原理,设定8个代表性火灾场景,通过数值模拟对设计方案进行分析验证。结果表明,该防火设计方案能够实现限制火灾大规模蔓延和保证人员安全疏散的设计目标,达到了规范要求的同等水平。更多还原

【Abstract】 Based on the technological requirements and space characteristics of a high-energy synchrotron radiation light sourceproject building, the main fire loads of office supplies, cables, etc. in it were analyzed. According to the difficulty of fire protection design in design scheme, preliminary solutions were put forward from the aspects of fire separation, fire extinguishing system,smoke exhaust system and electrical system. By using the principle of fire safety engineering, 8 representative fire scenarios were set to verify the design project by numerical simulation. The results showed that this fire protection design scheme can achieve the design goal of limiting the large-scale spread of fire and guaranteeing the safe evacuation of personnel, and it reached the same level as the standard requirement.更多还原
