Abstract

Earthen slopes experience considerable degradation in strength and stiffness during seismic activities. Past earthquakes have revealed the development of landslide and permanent movement of earth mass towards downstream. In this paper, a finite element analysis using GEOSLOPE on earthen slopes under static and dynamic loading due to earthquake has been carried out. The earthen slope is idealized as a plane strain two-dimensional model and base acceleration in the form of typical earthquake motion is represented as external loading. The performance of the slope including the stresses and displacements are analyzed. Further, the focus is on the determination of permanent displacement using Newmark’s sliding block model including parametric studies for both static and dynamic cases.

Static and Dynamic Behavior of Earthen Slopes in the Region of Uttarkashi, India

San Diego, California

Earthen slopes experience considerable degradation in strength and stiffness during seismic activities. Past earthquakes have revealed the development of landslide and permanent movement of earth mass towards downstream. In this paper, a finite element analysis using GEOSLOPE on earthen slopes under static and dynamic loading due to earthquake has been carried out. The earthen slope is idealized as a plane strain two-dimensional model and base acceleration in the form of typical earthquake motion is represented as external loading. The performance of the slope including the stresses and displacements are analyzed. Further, the focus is on the determination of permanent displacement using Newmark’s sliding block model including parametric studies for both static and dynamic cases.
