| Abstract: |
| In this paper, a simplified model for dam foundation dynamic interaction analysis in time domain is proposed in terms of the studying of the characteristics of the dynamic impedance of canyon cut in elastic half space. The numerical results show that the proposed model can not only effectively reduce the cost of the numerical analysis in time domain, but also retain the main factors for the dam foundation dynamic interaction analysis, and the results are reasonable, acceptable and very convenient for engineering application. |
