Design for Goupitan arch dam

摘要

Goupitan arch dam is 232.5 m high, the geological condition of dam foundation is complicate and there are many orifices in the dam body with large scale. The scale and technical difficulty of the arch dam go beyond the control of the active arch dam design criterion. Through referring domestic and overseas design experience and up to date research fruit of high arch dam, many analysis methods and model experiments are adopted, and through the analogy of other engineering, Goupitan arch dam's figure, stress, abutments stability, the whole safety, anti-seism and foundation treatment and so on are studied and analyzed. Finally the arch dam design meet safety, reliability, technical feasibility, economy and rationality.
