弹性基础上大型石油储罐的应力分析

对建立在松软地基上的大型石油储罐提出了油罐弹性基础的力学模型 ,得到罐壁环向应力和底板径向弯曲应力理论计算式 ,并将理论计算值与实测值和基于刚性基础的理论计算值进行了比较 ,发现基于弹性基础的理论计算值与实测值吻合较好

Stress Analysis of Big Oil Tanks on Flexible Foundation

The mechanical models of the flexible foundation of oil tanks were proposed for big oil tanks on flexible foundation,and the theoretical calculations of loop stress on the tank wall and the longitudinal bending stress on the bottom plate were derived,a comparison between the theoretical calculating value and the theoretical calculating value based on the stiff foundation and a comparison between the measured value and the theoretical calculating value based on the stiff foundation was made,and it was found out that the theoretical calculating value based on the stiff foundation was in a good agreement with the measured value.
