For the analysis problem of seismic response of the large vertical tanks with the base isolation, the interaction of soil and structure and the swing effect of storage tank are considered, start from the theory of fluid velocity potential, the boundary conditions of reservoir storage tank and tank wall are combined, liquid movement potential function and the corresponding the theoretical expression of base shear, overturning moment and the wave height are established. According to the equivalent principle of the shear and moment, the simplified mechanics model of base isolation tank with swinging effect is established, the motion equation of vertical storage tank isolation system that considers the swinging effect is established through using the energy principle. At the same time, take the 1500003m large scale storage tank for example, the dampening effect numerical analysis is carried on, and comparative analysis with simplified mechanical model of isolated system of no swinging effect is conducted. The results show that：the large scale storage tank with isolated device can effectively reduce the base shear of storage tank , have the poor control effects to liquid sloshing wave height, propose in high intensity area, under the promise of meeting the sloshing wave height, the upper structure of the storage tank can be designed on the basis of reducing the intensity.
