Semi‑Analytical Approach for Estimating the Viscoelastic Settlement of a Footing Resting on a Slope

چکیده مقاله

The safety of a foundation can be viewed from two different perspectives, bearing capacity, and the settlement. There are many articles focused on the bearing capacity of a foundation built near the slope. However, investigating the settlement of the foundation rest near the slope is very limited. In order to increase the safety of the structure, besides the elastic settlement, the study of time-dependent behavior of footing is of great importance in geotechnical engineering. In this research, a semi-analytical solution has been proposed to obtain the viscoelastic settlement of a footing adjacent to a slope. Based on the developed Airy stress function, distributed stress within the slope due to foundation load was computed analytically and then displacement has been acquired by using the finite difference method. The outcome of the proposed method was compared with COMSOL finite element software and good agreement between those was observed.
