earthquake response of slopes under massive loads

Many buildings and other structures have been constructed on sloping grounds. they may pose a considerable mass on the slope particularly in congested urban areas located on sloping grounds. traditionally, the additional mass is assumed as arigid body connected to the ground of slope. in this case, existing approaches for stability analysis of slopes and embankments can be directly applied to solve the problem with the consideration of additional mass to the soil mass above the slope failure surface. however, the complete inertial interaction of the structures supported by the slope is not considered in thisapproach. in this case, the amplification of the base shear transmitted to the ground may be significantly underestimated resulting in a non-conservative evaluation of the seismic slope stability. this paper aims to study the significance of the load of massive constructions on the slope stability problem with considering soil-structure interaction.
