Ultimate bearing capacity of strip footings lying on Hoek–Brown slopes subjected to eccentric load
A self-developed finite element limit analysis (FELA) code was employed in this study to investigate the stability of eccentrically loaded strip footings on rock slopes. The research emphasis of this study was on quantifying the inequality phenomenon induced by the slope and eccentric loads of different directions. The generalized Hoek–Brown yield criterion was embedded into the program to simulate the rock nonlinearity. Upper bound theorem, lower bound theorem and adaptive meshing technique were adopted for more reliable calculations. And stability charts were presented to illustrate the influences of various influential factors including the rock property, the slope angle and the footing position on the footing bearing capacity. Furthermore, transformation trends of failure patterns were analyzed for deeper insight into how the failure mechanisms evolving with different influential factors. Detailed design tables were summarized to facilitate the engineering practice and ensure the building safety.
