Summary: This study investigates the bearing capacity and deformation behavior of a rigid strip footing on coral sand slopes using model-scale tests. The results show that geogrid reinforcement significantly improves the bearing capacity of coral sand slopes. The bearing capacity increases with the increasing edge distance and the decreasing slope height and angle.

Summary: A parametric study was conducted using the finite element method to investigate the bearing capacity and failure mechanisms of strip footings on cohesionless soil slopes. The study quantified the variations in bearing capacity caused by different design parameters, footing dimensions, and soil properties. A multilinear equation was developed to predict the bearing capacity of the footing on the top of a slope, which showed reasonable accuracy.

Summary: This study investigated the mechanical response and geogrid fracture behavior of reinforced soil foundation through experiments and numerical simulations. It was found that increasing the number of geogrid layers significantly improves the bearing capacity and stiffness of the soil foundation.

Summary: This study examines the behavior of square footings on geocell-reinforced sand slopes. The results show that geocell reinforcement is more effective when the distance between the footing and the edge of the slope is smaller. The optimal depth of placement of the geocell layer is independent of the length of the geocell. Additionally, a greater vertical distance between the top and lower geocell layers leads to a decrease in the performance of the footings, and the width of the geocell has marginal impact on the behavior of the tested models.

Summary: The study reveals that using geotextile reinforcement layers and reducing the apex angle can significantly increase the ultimate bearing capacity of foundations near slopes. The farther the foundation is from the slope, the less adverse effect the slope has on the foundation; as the distance decreases, the effects of reinforcement and apex angle increase.

Summary: This study used a self-developed finite element limit analysis code to investigate the stability of eccentrically loaded strip footings on rock slopes. The research focused on quantifying the inequality phenomenon caused by the slope and eccentric loads in different directions. The program embedded the generalized Hoek-Brown yield criterion to simulate rock nonlinearity and employed upper bound theorem, lower bound theorem, and adaptive meshing technique for more reliable calculations. The study presented stability charts to illustrate the influences of various influential factors on the footing bearing capacity and analyzed the transformation trends of failure patterns for deeper insight into failure mechanisms.

Summary: This study analyzes the ultimate bearing capacity of an embedded strip footing on a rock slope subjected to seismic loading, showing that the magnitude of the bearing capacity factor decreases significantly with an increment in seismic loading, further decreasing with an increment in slope angle, and increasing with an increment in embedment depth. Stress contours are used to describe the combined failure mechanism of the footing-rock slope system under different embedment depths and types of loading.

Summary: The study investigates the bearing capacity of strip footings near rock slopes under pseudo-static horizontal earthquake forces using the upper bound finite element limit analysis combined with a mesh adaptive strategy. The generalized Hoek-Brown failure criterion is applied to describe the strength properties of rock masses. By considering different governing parameters, the seismic bearing capacity factor is determined and non-dimensional charts for design purposes are provided.

Summary: The stability of a footing-on-slope system under coupled eccentric and inclined loading is a significant concern in urban areas. The rigid plastic finite element method (RPFEM) was employed to evaluate the ultimate bearing capacity of an eccentrically inclined loaded footing placed on a sand slope. The study focused on assessing the influence of soil strengths, footing width, and slope geometry on the three-dimensional V-H-M limit load space to determine its uniqueness.

Summary: This paper presents a numerical study on the load-bearing performance of reinforced slopes under footing load. The results show that the soil dilation angle, footing location, and reinforcement design significantly influence the load-bearing performance, and the FELA method can effectively predict the magnitudes of bearing capacity, slope deformation, and mobilized reinforcement load.

Summary: This study investigated the pseudostatic bearing capacity of a strip footing placed close to an existing strip footing in cohesionless soil using the lower-bound finite-element limit analysis method. Results showed that the presence of the existing footing could improve the new footing's bearing capacity, but seismicity ultimately caused the new footing to withstand smaller accelerations. Increasing spacing generally reduced bearing capacity, except for specific cases with a friction angle of 40 degrees.
