| The paper research the theory and method in arch dam optimization specially mold the model of optimization ,choose the method of optimization design ,apply the approximate re-analysis technology to optimization design of arch dam. Restrain alteration size is applied to improve the efficiency of structure optimization. Approximate reanalysis technology is introduced to save the time of stress reanalysis . The multi-cantilever method and the finite element method is combined to analysis the arch dam ,to enhance the capability of practical applications in engineer. The program is applied to solve the optimization design of Jiang kou arch dam. |
