Abstract
China is addressing the significant challenge posed by the construction of several 300-m-high arch dams for the effective use of hydropower resources. Limited experience has been gained globally in the construction of super-high arch dams. Moreover, the present design codes are based on past experiences with arch dams with significantly lower height. Stress computation consists of many analytical simplifications. In addition, numerous questions may be raised regarding the reliability of this computation for application to super-high arch dams. This study therefore presents an integrated analytical approach to simulate the actual working performance of super-high arch dams. This approach emphasizes the significance of the analytical descriptions on four actual factors: (1) actual material, (2) actual structure, (3) actual load, and (4) actual process. Furthermore, the effectiveness of the actual working performance simulation has been proven by updated engineering practice.
