摘　　要：采用数学计算和FDS软件模拟对缩小尺寸的油罐火灾模型试验进行安全性分析,得到火焰跳动频率、倾斜角、火焰高度和热辐射安全距离等参数数据,与实际的模型试验进行比较。模拟油罐的直径为1.7m、高度为1.7m,模拟试验中罐底距离地面0.3m,油罐上端开口,环境风速为0m/s及5m/s。结果表明,数学计算和FDS软件模拟的各种数据取最小值时和模型试验最为接近,因此该安全性分析具有可行性,同时建议保守地采取FDS下风向数值作为试验的安全距离。Using mathematic calculation and FDS to analysis the security of oil tank fire＇s small scale model test, the characteris- tic parameters of fire, such as flame pulsation frequency, flame tht angle, flame height and safety distance were gotten. Final- ly, these data are verified by moclel test. The diameter of oil tank is 1.7 m and the height is 1.7 m; the tank is 0.3 m above the ground in the test and is open at the top~ the wind speed is 0 m/s or 5 m/s. The results showed that the minimum of ＂math ematic calculation and FDS＇s data were most close to model test＇ s data. It is feasible to analysis safety distance of oil tank fire model test using this methods. In addition, it is more secure to regard FDS＇s downwind data as safety distance in experimental research.
