Performance of footing with single side micro-piles adjacent to slopes

This research was initiated in order to investigate the capability of rigid strip one side micro-piles footings in stabilizing sand slopes. A physical model was designed and constructed for micro-piles footings resting on dense sand. Measuring devices were arranged; load-settlement measurements of the model footings were recorded; photos were captured and observations were documented. Different footing configurations located at variable distances from slope edge were tested; five groups of micro-piles depths were inspected and different eccentric vertical so as oblique loads were examined to investigate its capability of stabilizing the slopes. Measurements were plotted and analyzed. Comparison was carried out among the inspected cases. Results indicated that a significant enhancement to the bearing capacity of single side micro-piles footing was documented with the increase of micro-piles depth. It reached about 7.9 times that of footing without micro-piles.
