摘要
利用有限元法,对带贴板补强的球罐人孔结构由内压产生的应力进行分析计算,给出了应力分析及特点。并通过大量分析计算,探讨了不同宽度的补强板对补强效果的影响,结果表明按等面积补强法设计的补强结构能够满足基于极限分析与安定性分析的补强原则的要求;对于贴板补强,补强板的宽度在一定范围内变化,对补强效果影响不大。
It utilizes the limited element method to calculate & analysis the stresses caused by the internal pressure of the spherical holder manhole construction with re-inforced plate to give out the stress distribution &
its special characteristics. Through large quantity of analysis and calculation,it discusses the effect & result of re-
inforcing by different width of the plates. The result expresses the method of equal area reinforcing in design can
satisfy the requirement based on limit analysis & stability analysis reinforcing principle. The width of the reinforcing plate varying in a certain range does not effect the reinforcing result too much.
