摘要
针对西安市新建成的某地铁站基于国际上通用的热烟测试标准进行了热烟测试。测试指标包括:各系统的联动状况,站台、站厅内的温度场变化,站台、站厅、设备房区域的烟气扩散情况;站台、站厅危险高度处温度变化;安全疏散时间;特征流速和特征时间等。基于测试结果,对模拟火灾发生后的站台不同部位的温度、烟气速度和防排烟等系统联动特性进行分析,表明本车站通风排烟等系统的工作效果满足设计要求,但仍存在进一步优化的空间。
In this paper,focusing on a newly built Xi'an Metro station,based on internationally accepted standards,hot smoke testing were conducted.The tested indexes include: cooperation situation of all systems,temperature field variation in the station platform and station hall,smoke diffusion situation at the station platform and the equipment house zone,temperature variation at the dangerous height in platform and station hall,safety evacuation time,characteristic flow-velocity and characteristic time and so on.Based on the test results,the cooperation characteristics of all systems under the condition of simulated fire were analyzed,including the temperature system,smoke velocity system and the smoke control system in different parts of the platform.The analysis results show that the effects of ventilation and smoke control system at this station can meet the design requirements,yet there is still something that should be optimized further.
