Abstract

According to current practice, analyzing the stability of an earth slope under seismic conditions involves applying a pseudo-static seismic load in a conventional limit equilibrium analysis or performing a displacement analysis based on the analogy of a rigid block on an inclined plane. This paper reviews the development of currently used approaches of seismic slope stability analyses, available remediation methods, and design considerations. It examines the issues of shear strength degradation, strain incompatibility, and presents three case histories of projects located in areas of high seismicity where some form of reinforcement was used to obtain seismic slope stability.

Reinforcement of Slopes for Seismic Stability

Arlington, Virginia

According to current practice, analyzing the stability of an earth slope under seismic conditions involves applying a pseudo-static seismic load in a conventional limit equilibrium analysis or performing a displacement analysis based on the analogy of a rigid block on an inclined plane. This paper reviews the development of currently used approaches of seismic slope stability analyses, available remediation methods, and design considerations. It examines the issues of shear strength degradation, strain incompatibility, and presents three case histories of projects located in areas of high seismicity where some form of reinforcement was used to obtain seismic slope stability.
