Flashback Friday: Seismic Stability White Paper

This paper written in-part by Rhea President Marcy Johnson in 1986, examines the slope stability under earthquake conditions of a dredged slope in Charleston, South Carolina area. Both circular failure surfaces and wedge-type failure surfaces are examined using limit equilibrium techniques. The effect of variations in river water level is analyzed. Of particular interest in this study, is the effect of the loose sand layer at the interface of the marl and the overlying soils and its influence on slope performance.
