Comparative Safety Analyses of Slope-Shallow Foundation Interaction under Static and Dynamic Loading Conditions

Abstract

This study is focused on the safety analysis of the shallow foundations located on cohesive homogenous slopes that has different shear strength characteristics. Static and dynamic analyses have been conducted with a well-known commercial finite element logic-based two dimensional numerical software. Dynamic analyses are performed with regard to the consideration of the Samos-İzmir earth-quake that happened in 30 October 2020. The change of the slope geometry depending on the differentiation of the slope height and inclination is also considered. The interaction between the slope-shallow foundation is investigated regarding different relative distances of the foundation from the slope edge and considering various loading magnitudes for the foundation. The results of the analyses are evaluated in terms of the factor of safety values to interpret the degree of the effects of foreseen variants on the integrated system stability.
