Abstract

Strain energy of dam body and its sensitivity to the deformation modulus of foundation are taken as objective functions, robust feasibility constraint of stress is proposed with the consideration of uncertain deformation modulus of foundation, and a robust optimization model is established for shape design of arch dams based on strain energy. In the solution process, firstly, utopia solution is obtained by single-objective optimizing of each target. Secondly, based on grey incidence analysis method, a close correlation degree is constructed to measure the degree of closeness of a solution and utopia solution. Finally, robust feasibility optimization model is transformed to a single-objective optimization problem. The calculation of a planned arch dam indicates that compared to the solution of linear weighted method, the optimal design of fuzzy nearness method is closer to utopia solution and is with better dam stress state.
