The invention discloses a method for realizing concrete dam storehouse surface design data structuralization. The method comprises the following steps: decomposing logging data items of storehouse surface design, and establishing a correlation and operation rule between the data items, thus realizing automatic filling and reporting of the storehouse surface design data and automatic computing of a project amount. According to the method disclosed by the invention, data correlated to the storehouse surface design can be structured, associated data can be correlated and can be systematically and automatically computed according to a computational formula, and a manual computation process is changed to be automatically completed by a computer, so that the working efficiency of the storehouse surface design is greatly increased.
