Three-dimensional finite element analysis for concrete arch dam of Chahuadun reservoir

Concrete arch dam is main building in water conservancy engineering, arch dam has many advantages, such as elegant structure, mechanical performance is good. Arch dam is widely used in water conservancy engineering. In this paper, finite element simulative analysis is proceeded for the concrete arch dam of Chahuadun reservoir. Deducing variation law of the dam´s stress and displacement in construction process and operating process. The analytic results are shown, concrete arch dam of Chahuadun reservoir is reasonable structure, and every index meets the requirements for design.
