Block Element Analysis for Earthquake Response of Joint Rock Slope
In this paper, the Block Element Method (BEM) for dynamic analysis is developed and applied to historical analysis of seismic stability of a rock slope. Combine the idea of viscous-spring boundary with the theory of BEM, the artificial boundary condition of BEM is formulated, which can eliminate reflection of the seismic waves from the boundaries of the calculating domain. Also, the relationship between the displacement and the stiffness of discontinuous is adopted in the dynamic block element method. The corresponding program is written by FORTRAN language and the application of the intake slope demonstrates the capacity of this method.
