摘　　要：利用数值模拟技术研究了电缆竖井不同高度和通风条件对细水雾灭火效果的影响,按典型高低压电缆井断面情况,基于火灾动力学软件,模拟了细水雾灭火系统在电缆竖井中不同通风条件下的控火和灭火效果,同时对细水雾灭火系统在电缆竖井中的形式、喷头布置方式等进行说明,得到在限定条件下的火灾规律性结果和相应的应用边界条件等结论,为电缆竖井防火实验研究和工程设计提供参考。The technology of numerical simulation is applied to study the fine water mist fire extinguishing effects due to different heights and ventilation conditions of cable shafts.Based on the typical high and lowvoltage cable shaft sections and fire dynamics software,the fire control and extinguishing effects of fine water mist fire extinguishing systems are simulated under different ventilation conditions in cable shafts,and the form of fine water mist fire extinguishing systems in cable shafts and the arrangement of spray heads are explained,which draws the conclusions on the regularity of fires under limited conditions and the corresponding application boundary conditions,offerring reference for experimental research and engineering design of cable shaft fire prevention.
