剪刀楼梯应用于大型批发市场疏散的探讨

Discussion on application of scissors staircase in the evacuation of large wholesale market

结合某市编制大型专业批发市场消防技术规范的需求,针对批发市场采用剪刀楼梯用于人员疏散的情况,采用人员疏散模拟分析软件设计典型大型专业批发市场人员疏散场景,分析采用剪刀楼梯对于人员疏散安全性的影响。研究结果表明,剪刀楼梯的疏散宽度、疏散距离是影响人员安全疏散的重要因素,均匀分布的剪刀楼梯对人员安全疏散效率的影响较小,过长的疏散距离会大大降低疏散效率。

Combined with the formulation of code for fire engineering design of professional wholesale market, based on the application of scissors staircase in the evacuation of large wholesale market, using people evacuation simulation sofeware, the classic evacuation scenarios were designed, and the influence of scissors staircase on people evacuation was analyzed. The results showed that the width and evacuation distance of scissors staircase are the main influencing factors; scissors staircase with uniform distribution has little influence on the efficiency of evacuation; overlong evacuation distance will reduce the efficiency of evacuation seriously, therefore, scissors staircase can be applied in Safety evacuation on the basis of quantity analysis of specific circumstances of different buildings.
