摘　　要：10万m3储罐在原油储备中应用越来越广泛,其强度安全要求显得更重要。通过有限元软件ANSYS,对水压试验工况下的10万m3大型外浮顶式原油储罐进行了分析,获得了储罐各部位的应力分布情况,用分析设计标准对主要部位进行了应力评定并确定了关键部位,强度评定的结果表明,在最高液位下储罐可以安全运行,不会发生强度不足失效。The 100,000 m^3 tanks were used widely in the field of crude oil storage,and their intensity came to more important. Finite element software ANSYS was adopted to analyze the 100,000m^3 largescale floating crude oil tank with the topmost hydraulic state ,and the stress distribution of all parts of the tank was obtained. The assessment for the tank＇s stress was done,according to the analysis design code, and the key part was determined. The results of the infensity assessment showed that the tank was safe in the topmost hydraulic state.
