Based on the previous work, this paper further studied the optimization design problem of double-curvature arch dams, and presented the geometric models, discrete geometric models and mixed geometric models of the five-center circular double curved arch dam and the parabolic double curved arch dam. The characteristics of arch dam geometric models were analyzed and reviewed. Several methods for different geometric models were proposed through the reduction of design variables. Two-stage optimization methods and boundary search methods were presented. In China, double curved arch dams Optimized design has begun to be applied to practical projects with significant results. This article describes some of the strategies that have been taken to get the optimal design of arch dams into practical use.
