Abstract
Concrete arch dam as an important hydraulic structures, in recent years has been widely used in water conservancy projects. Gucheng Reservoir is located in the ancient city of Yanqing County in Beijing, where is 10 km from the dam to the county, control drainage area above the dam 119 km ,which is an irrigation project, combined with the utilization of water projects for flood control, power generation and so on. In this paper, general finite element calculation software for concrete hyperbolic arch dam of Gucheng reservoir simulation analysis gives arch stress, deformation distribution in the course of construction and operation. The results for the design and construction of concrete hyperbolic arch dam structure provides a frame of reference, which has a certain theoretical significance. Arch upstream surface of the circumferential stress are substantially compressive stress, in addition, the first principal stress value smaller of the arch, which is able to meet strength requirements.The structure is safe and reliable.Meanwhile the deformation values is smaller of the arch, also to meet stiffness
