Abstract: Ground foundation adjacent to slope is already a universal foundation form. In view of the asymmetric failure characteristic of strip footing adjacent to slope, a bilateral failure model is developed. In this model, the double asymmetrical features are that the rigid sliding block sizes under both sides of strip footing or the geometry shape of the same slider is not identical. Based on the aforementioned mode, a new method for ultimate bearing capacity of strip footing adjacent to slope are put forward by adopting the upper-bound limit analysis method and optimization theory. The proposed precedure can reflect the influences of both the failure mode and the distance between strip footing and slope top on the bearing capacity of strip footing. At the same time, it could be degenerated well to determine the ultimate bearing capacity of the ground foundation. The feasibility, rationality and universal applicability of the approach are verified by the comparative analysis of results of engineering cases with existing methods in literature and the one in this paper.

Key words: ground foundation adjacent to slope, upper-bound limit analysis, strip footing, ultimate bearing capacity, asymmetric failure mode, optimization
