| 摘 要： | 依油罐破裂时孔口所在高度不同，将罐体沿高度分作５个区段，分别进行了荷载计算，另外，针对大型贮油罐裂缝多发生在罐壁底部的特点，就防火堤内充满溢流液体的不利工况，通过有限元分析，探讨了防火堤内侧坡度对事故荷载产生的影响，给出了相应荷载分布曲线。

| Abstract: | in terms of the indeterminacy of crack levels and the variety of the actionso f jet on fire-dyke,five divisions of oil tanks in vertical direction are defined and the corresponding loadings are computed.Based on the specific characteristic of the cracks,i.e.,lowlevel and horizontal orientation,and provided that the fire-prevention area is full ofspillingwater,the influences of the slope of the innerside of the fire dyke on the emergencyloading are investigated by finite element methods.A series of curves of loading-levels andsome beneficial conclusions are given. |

| Keywords: | fire-dyke free non-submerged jet two-dimensional steady state flow finite element methods |
