Seismic Hydrodynamic Forces on Rock Slopes

Abstract

A finite element method of analysis for seismic response of fluid‐structure problems is presented. Displacement model finite elements are used in the fluid region, leading to simple fluid‐structure interface conditions. The methodology has been used in a parametric study of seismic hydrodynamic forces on rock slopes. Parameters considered in the study are: height of the slope; depth of water; slope of the rock face; and, the earthquake base motion. A method for evaluation of seismically induced movements of submerged rock slope is presented. Calculation of seismically induced movements are a major step in the evaluation of the seismic stability of submerged rock slopes.
