Simulation Calculation of Concrete Gravity Dam for Xiyu Reservoir During Operation Period

Abstract

Concrete gravity dam is a common hydraulic structure,in order to have a clear understanding for concrete gravity dam in the operating process , researching stress and deformation distribution of concrete gravity dam. This paper adopts the universal finite element calculating software to simulate and calculate concrete gravity dam for Xiyu reservoir during operation period, and gives stress and displacement values on the typical section of gravity dam under the condition during operation period, and analyses calculation results, research results can provides certain theoretical basis for design and construction of concrete gravity dam. The results showed that, in the operating process, stress and deformation values of concrete gravity dam for Xiyu reservoir mainly related to water pressure and earthquake action, but the dam’s stress and deformation values are smaller, the stress and deformation values can meet strength and stiffness requirements.
