Abstract
Placement of shallow foundations near or adjacent to slopes reduces their seismic and static bearing capacities. In this paper, the seismic behavior of shallow foundations adjacent to sandy slopes has been studied using a two-dimensional finite element method. Most of the previous studies have focused on upper bound solutions in limit state analysis framework via pseudo-static loading, and the effects of actual seismic loading such as loading frequency effects, acceleration amplitude above 0.30 g, non-linear dynamic analysis, and so on are ignored. The shallow foundations are located at a certain distance from the slope crest (i.e., d = 0.5b, 1.5b and 2.0b). The slope inclination angle studied in this paper is 25° (1 V: 2 H). The analyzed slope is composed of medium dense sand. The two elastic–perfectly plastic Mohr–Coulomb (MC) and hardening soil (HSM) constitutive models have been considered to investigate the effect of plastic behavior of the sandy soil. Innovatively, the actual seismic behavior of the slope, shallow foundation and the direction of the seismic responses have been studied. The results show that the structural and geotechnical responses of the HSM model are in most cases up to 30% larger and more conservative than the MC model responses. This shows the importance of using the HSM model in the study of seismic stability of slope and foundation.
