摘要	To engineering analysis and application, based on velocity potential theory, the liquid movement potential function and the expression of base shear, overturning moment were established. The floating roof was simplified as a rigid, homogeneous plate. Starting with plate vibration equation and boundary conditions of the plate-liquid surface interaction, the sloshing analysis equation and the wave height expression were constructed. A simplified analysis mechanical model was established by adopting base shear equivalent and the same way to acting energy, and the system motion equation was given according to the energy principle, given the impact of the relevant parameter. Selected 50 000 m3 storage tank, the response spectrum and time history analysis were contrasted. The results showed that: base shear force, bending moment and wave height were close to related research literature and finite element solution, the research result is feasible, it could meet the engineering design needs.
