“…The numerical simulation of the stability analysis includes the finite element method [2,3], the discrete element model [4], and the fast Langrangian analysis of continua (FLAC) [5]. Compared with vertical loads, inclined loads should take into account the effect of the inclination angle [6][7][8][9][10]. The methods of the ultimate inclined failure load of the foundation on the undrained soil slope include the empirical approach [11,12] and the finite element limit analysis (FELA) [13,14].…”

The failure mechanism is the key problem for calculating the inclined failure loads adjacent to the undrained soil slope. Based on the undrained slip line field and boundary value problems, a new failure mechanism is proposed to evaluate the inclined failure loads adjacent the undrained slope. The rationality of the proposed method is proved by the definition of the ultimate load and the finite element upper bound analysis (FE-UB). It is not reasonable to assume the failure models since the failure models vary with the inclination load and angle. The proposed method gives a new evaluating indicator, which first calculates the inclined failure load and then determines the failure models.

“…It is a complex problem to calculate the ultimate inclined load of a shallow foundation adjacent to the slope. The inclined load and slope reduce the bearing capacity of the soil [ 1 ]. Current research gives exact solutions or empirical equations for the effect of inclined loads on the bearing capacity of foundations on the horizontal ground to calculate the damage loads.…”

A new failure mechanism is proposed for calculating the ultimate inclined load adjacent to the slope, i.e., the slope is in the limit state when the critical slope contour and the slope surface are at the critical position where two intersections will occur. The conventional view is that the critical slope contour calculated by the method of characteristics has only a concave shape. This study found that the critical slope contour changes from concave to convex when the inclined load imposed on the slope top surface increases. The feasibility of the proposed method is verified by the finite element limit analysis (FELA) and the definition of the ultimate load. The parametric analysis showed that the current method of characteristics (CMOC) overestimated the ultimate inclined load and gave an incorrect conclusion since it assumed larger failure models at a low strength ratio or large friction angle. The proposed method does not require assumption or search of the failure models, and it can solve the shortcomings of CMOC.

“…The majority of the above mentioned studies focused on foundations resting on a horizontal ground, however, many of these structures are placed above or near slopes. There are some investigations that have been conducted to calculate the ultimate load carrying capacity of strip footings subjected to central loading near reinforced slopes without voids [27][28][29][30][31]. In contrast, strip footings adjacent to reinforced slopes with voids have received little experimental and theoretical/numerical research.…”

This paper presents the results of the numerical analysis undertaken to investigate the effect of the underground void on the load-bearing capacity of a strip footing placed on an unreinforced and geogrid-reinforced sand slope with a void inside. The failure mechanism of the soil was also investigated. The numerical model was obtained using 2D plane-strain FEM analysis (in Plaxis software), in which the nonlinear Mohr-Coulomb model was utilized. The effects of various parameters such as the number of geogrid layers (N), the vertical distance ratio between the top of the cavity from the base of footing (H/B), the horizontal distance of void centerline to the footing center (X/B), on the behavior of footing are studied in this research. The results indicate that there is a critical zone under the footing in which the existence of void has no influence on the bearing capacity and stability of the footing. In addition, the use of geogrid reinforcement reduces the settlement and enhances bearing capacity. Finally, the bearing capacity factor and failure mechanism increase with increasing horizontal and vertical void distances ratios (X/B and H/B) and reinforcement layers.
