PERFORMANCE OF STRIP FOOTINGS ON SLOPE REINFORCED WITH INCLINED PILE

The footing that placed on slope surface results in decreasing the bearing capacity of soil. The pile reinforcing the slope may affect the bearing capacity of footing and factor of safety of slope. The piles installed within the slope mechanically provide a resistance to slope system along the failure surface. The present work was focused on the analysis of strip footing behavior on slope with and without pile using a finite element software PLAXIS 2D. The various parameters considered for present work includes location of pile from slope crest, inclination of pile, effect of pile length and effect of width of load. The results indicated that stabilizing pile has a significant effect in improving the bearing capacity and factor of safety of slope. The bearing capacity of footing was found to be maximum when slope was reinforced by pile at crest. For smaller width of strip, the factor of safety of slope was maximum when pile is placed at crest while for larger width the pile location at 0.5 horizontal widths of slope gave maximum factor of safety.
