The generalized fuzzy optimum method is introduced into earth rock dam design, and the membership function under constraint conditions and design variables are studied. Based on deterministic cross section optimal design for earth rock dams, a mathematical model of generalized fuzzy optimum is established for dam cross section design. The model is converted into deterministic cross section optimal design by the satisfaction degree method. A practical optimum design of a dam section proves the optimal form to be reasonable.
