储罐下沉式人孔开孔补强分析

Analysis of the Opening Reinforcementof the Tank on the Sinking Manhole

摘要: 为研究储罐下沉式人孔局部结构强度，采用压力容器开口补强理论分析和有限元仿真方法对人孔处的静强度进行分析，通过对不同罐径储罐人孔的有限元仿真和理论强度校核，研究了储罐下沉式人孔的开孔补强和应力分布情况，为储罐设计安全提供参考。

Abstract: The static strength of the manhole is analyzed by means of the open reinforcement theory and the finite element simulation method to study the local structural strength of the sinking manhole in the tank. The opening reinforcement and the stress distribution of the sinking manhole of tank of different tank diameters are studied by the finite element simulation and theoretical strength val-idation of manhole, which provide a reference for the design safety of the tank.
