Effect of Soil and Rock Interface Friction on the Bearing Capacity of Strip Footing Placed on Soil Overlying Hoek–Brown Rock Mass

In the present study, the ultimate bearing capacity of a strip footing placed on a soil layer overlying a rock mass layer is determined by considering the interface friction angle (δsr) between the soil and rock mass layer. The lower bound finite-element limit analysis in association with the two conic optimization techniques, namely second-order cone programming (SOCP) and power cone programming (PCP) are utilized to model the failure of the...
