Hongyan hydropower station is located in Maotiao river, in Xiuwen county of Guizhou province,it is a power generation project and designed the third class structures, Pivotal Project are composed of dam, water diversion tunnel, powerhouse, subsidiary dam, etc. Dam is concrete double curvature arch dam. Valley is narrow where dam site is located, V-shaped, and provides good terrain for dam construction. The stress and strain of arch dam structure not only are the index of arch dam structure rigidity, but also are the basis of identifying whether the arch dam structural damage occur. Horizontal section and vertical section of double curvature arch dam are all curve shaped, it is the most representative in the arch dam type. This paper adopts the universal finite element calculating software to design and simulate double curvature arch dam of hongyan hydropower station, and gives stress and deformation distribution of arch dam during construction and operation period. Analysis results can provides certain theoretical basis for structure design and construction of double curvature arch dam. Keywords-Hongyan hydropower station; Concrete arch dam; Structure design; Simulation analysis; Stress distribution
