Abstract:
The dynamic response of the dam-structure interaction system under the action of earthquake and wind was analyzed based on VOF method. Under the three working conditions of empty reservoir, dam-reservoir interaction, and dam-water-wind interaction, the dynamic displacement, absolute acceleration, and hydrodynamic response of the dam under the earthquake and wind load were calculated and analyzed. Meanwhile, the tracking of free surface based on VOF method verified its reliability and superiority. The results indicated that the interaction between the reservoir and dam is remarkably nonlinear. The dynamic displacement and absolute acceleration can be increased by the dam-water interaction. Furthermore, wind had no impacts on the dynamic displacement and absolute acceleration of the dam, but significant impacts on hydrodynamic pressure.
