... were obtained from horizontal boreholes drilled into the wall of a drift excavated in soft sedimentary rock. This allowed the vertical stress variation with distance from the drift wall to be determined up to a depth of 5 m. The vertical stresses determined using rock cores varied with distance...

The variation of ultimate bearing capacity and slope angle for un-reinforced soil (Mehta, 1998) is also plotted in the above mentioned figure for comparison. It is evident from Figure 3 that as the slope becomes steeper...
