本文采用有限单元法探讨了软粘土地基上圆形贮罐上部结构、垫层和地基共同作用对贮罐沉组和基底反力分布的效应,以及对在地基固结过程中贮罐沉降的发展过程和地基中孔隙水压力分布的影响。文中以一油罐为例,将计算与实测结果作了比较分析,说明考虑上部结构,垫层和地基共同作用是必要的, In this paper, the finite element method is used to investigate the effect of the interaction of the upper structure of the circular tank on the soft clay ground, the cushion and the foundation, and the distribution of base counterforce, and the development of the settlement of the tank during the consolidation of the ground. The influence of pore water pressure distribution on the process and foundation. In this paper, an oil tank is taken as an example to compare the calculation and the actual measurement results, which shows that it is necessary to consider the joint action of the superstructure, cushion and foundation.
