五店市历史传统街区建筑群防火间距研究

针对执行现行消防技术标准与保留传统建筑风貌的矛盾,以晋江五店市传统街区为对象,采用数值模拟方法研究不同楼间距对相邻建筑所受火灾辐射热流的影响规律,对街区内的典型建筑防火间距进行重新评估,使其既满足历史街区风貌保护要求,又能达到预防火灾的目的。

Study on fire prevention spacing of Wudianshi historic district

The rapid urbanization process of China has brought new problems on the fire protection planning of historic districts. One of the most important problems is how to balance the contradiction between current fire prevention code and historic architectural style maintenance in the design of fire prevention spacing. Based on the principle of performance-based fire safety design, the influence of building interval on the radiation heat flux received by an adjacent building is studied using CFD simulation to determine the critical fire prevention spacing for the typical buildings in Wudianshi historic district. This method provides a solution satisfying both the district style maintenance and the local fire safety. A series of improvement plan for fire protection for the district is proposed according to analysis results.
