- Abstract
- The present study deals with the hydrodynamic effect of earthquakes on a three-dimensional dam-reservoir system. Analytical solutions in closed forms have been obtained when the reservoir is circular or semi-circular in shape. The effects of surface waves and compressibility of the fluid in the reservoir have also been included. In the case of no surface waves, it was found that the in-phase component of the hydrodynamic pressure increases with the depth of the reservoir and attains a maximum value at the base of the dam. In the presence of surface waves, the in-phase component was slightly reduced for small values of the wave-effect parameter C. However, for large values of C, the pressure distribution was found to be oscillatory. Resonances were found to occur when the ratio of the fluid depth to the period of the ground motion was greater than 360 m/sec.
