2.3 Bearing capacity of footings on slopes 4 The overall slope stability should be checked for the effect of the footing load.At least a few trial circles should touch point c(on the edge of base)as well as other trial entrance points on top of and on the slope. The ultimate bearing may be computed by any of the equation of Table 2.1;however,the author suggests using the Hansen equation modified to read as follows: qult=CNc'Scic+qNgSgig+1/2YBNy'syiy Obtain the Nc and Na factors from Table 2.3. The d factors are not included in the equation since the depth effect is included in the computation of the ratios of areas.2.3 Bearing capacity of footings on slopes ▪ ④ The overall slope stability should be checked for the effect of the footing load.
