| 摘 要： | 以3×103 m3立式拱顶储罐为研究对象,针对GB 50341对弱顶结构的要求,评价储罐的弱顶性能。建立储罐的空间模型,采用有限元法对储罐进行应力分析,计算得到储罐在空罐、半罐、满罐下的应力分布和强度破坏压力。通过对储罐弱顶影响因素的分析,找出影响储罐弱顶性能的主要因素,并探讨了使该类储罐设计成弱顶的可能性。

| Abstract: | Researching for 3×103 m3 vertical dome tank,according to the weak roof requirement of GB 50341 standard,the weak roof performance of tank was evaluated.Establishing tank space model,using the finite element method for tank stress analysis,stress distribution and intensity breakdown pressure of empty tank,half tank and full tank were calculated.The main factors of weak roof performance of tank are found out,and the possibility of which the tanks are designed into weak roof tanks is discussed through the influencing factors analysis of weak roof. |
