Abstract: As a widely used natural curve type, catenary has proved its good performance in all application areas, but has not applied to the design of arch dam yet. Therefore, based on the well developed arch dam system, by referring to the design method of arch dams with common axis and using computer aided design, we tried to use catenary as the axis type to establish the design method and theory of a new type of arch dams, which would enrich the concrete arch dam system.
