Zusammenfassung:The invention discloses a method for obtaining a theoretical minimum tide surface model of an unknown sea area, and the method comprises the steps of selecting a minimum tide level through employing atide height formula, and forming a theoretical minimum tide surface grid of an engineering sea area; and performing refined fine adjustment on the model by adopting a theoretical minimum tide surfaceknown value of an existing tide inspection station to form a final theoretical minimum tide surface model. According to the invention, a Vladimirsky model is not used, the theoretical minimum tide surface is determined through calculation and modeling of the astronomical minimum tide longitude forecasted in 19 years of all tide division, and the precision is remarkably improved through inspection. The number of offshore fixed-point tide stations can be remarkably reduced, and considerable economic benefits are generated; and the efficiency is remarkably improved, the precision can reach the centimeter level, and the r
