Abstract

The seismic safety of the dam involves the safety of people's life and property, and even affects the overall safety of the national economy. One of the key of technical issues in this subject is the more complete fluid-structure interaction(fsi) theory and the more accurate calculation method. In order to solve the problem of dynamic fluid-structure interaction in gravity dam, a 2.5d semi-dynamic theoretical model and a numerical solution method are established by using fluid slice method. The numerical experiment of seismic sress response is compared with three-dimensional model. The results show that the stress response of the 2.5d semi-dynamic model of gravity dam can well reflect the fluid- structure interaction behavior and effect of seismic gravity of concrete gravity dam.
