Abstract
Seismic slope stability analysis is a topic of great interest in geotechnical and geoenvironmental engineering particularly in seismic area in fact the occurrence of earthquake induced landslides is documented in many recent post-earthquake damage report (Japan 1993- 199 Greece 1995, Turkey 1999). Generally saturated slopes of loose sand or silty-sand and earth dams and embankment resting on low cohesionless soil deposit are highly susceptible to liquefaction-induced damage and during strong earthquake several landslides caused soil liquefaction may occur. In this paper a numerical model to evaluate seismic response of submerged cohesionless slopes is described. Slope stability conditions are evaluated taking into account the inertial effect of seismic forces and the earthquake induced pore pressure which reduce soil effective stress state. Displacement analysis has been performed using an extension of Newmark’s sliding block model for rotational failure mechanism and taking into account the reduction of slope critical acceleration due to changes in pore pressure Applying the proposed model a numerical analysis has been performed in order to point out those parameters which mostly affect seismic slope response and some useful stability charts are provided.
