Seismic Response Analysis of the Underwater High-rise Independent Intake Tower
In this study, the seismic response of the high-rise intake tower in the spillway tunnel of a hydropower station is analyzed. The intake tower is in underwater and independent. The commercial finite element software ANSYS is used to develop a 3D dynamic finite element analysis model of structure-water-foundation. A simulation method of hydrodynamic pressure of the underwater intake tower is studied. The dynamic characteristic of the underwater intake tower is analyzed. Time history analysis method is used to calculate the seismic response of the intake tower structure under the horizontal earthquake. The most unfavorable position of the intake tower for earthquake occurrence is given and the corresponding shock absorption measures is provided. The results provide science reference for the engineering design.
