Seismic Response Analysis of Flow-structure Coupling of Gravity Dam Body-foundation-reservoir Based on ANSYS
With the continuous development of water conservancy in China,many large-scale water-retain-ing structures have been established,such as concrete gravity dams.At the same time,China is a country with a high incidence of earthquakes,so the seismic design of concrete gravity dams cannot be ignored.In this paper,the finite element model of dam-reservoir water-foundation interaction is established by ANSYS fi-nite element software for engineering examples,and the modal analysis and seismic time history analysis are carried out respectively,and the results show that the fluid-structure interaction method is more beneficial to seismic design than the additional mass method.
