Sequential quadratic programming(SQP)method, one of nonlinear optimization methods, is adopted to optimize section configuration of roller_compacted concrete(RCC) gravity dams. The material distribution of RCC gravity dams and combination of more optimizing variables are considered in the process of optimizing. The computation result of the project example based on the method shows that the optimization design program can decrease efficiently cost per unit width of RCC gravity dam body and gain structurally efficient and economical section configuration.
