Abstract

To obtain the more accurate response of the ARCH DAM in frequency domain, the DYNAMIC ANALYSIS should be carried out by imposing the DAM-FOUNDATION ROCK INTERACTION effects. To do so, the foundation rock is usually considered as a substructure, and its IMPEDANCE MATRIX is computed separately. In this article, the IMPEDANCE MATRIX for the static case is obtained by utilizing the three-dimensional BOUNDARY ELEMENT method, and so, the flexibility effect of the foundation rock is imposed. In this approach, the geometry of canyon could be quite arbitrary and this has become possible due to the fact that a 3D BOUNDARY ELEMENT formulation is applied for foundation rock domain. In the results section, the seismic responses of a real ARCH DAM are presented, and they are verified by the results of the well-known FINITE ELEMENT method. It should be mentioned that the analyses are performed by the special purpose program developed.
