The design theory of roller gate has been systematized laying more emphasis on practical formulas than theoretical ones and the design procedure of the existing gate facilities is reviewed and analyzed on economical viewpoint and safety factor. The design theory of Timo-shenko, the thechnical standards for hydraulic gate and penstock of Japan, and the design standards for waterworks structures of Germany are applied to the study of optimal design of a gate leaf.<br/> In this study, gate leaf which is now being operated for water control at the seadike, estuary dam and reservoir dam are adopted as a model, and a new design method by the computer is proposed through the variation of design elements within practical ranges.<br/> As a result, safety factor and economical design can be made by using T-beams to the horizontal and vertical beam of the gate leaf instead of H-beams used in the existing seadike roller gate at Asan, and total weight of gate leaf is reduced by the present optimization.
