Pile foundation becomes the immediate choice when the shallow footing foundation is not possible. Pile foundations have been successfully adopted across the wide range of ground conditions with suitable design and construction aspects. However, when piles are to be used close to or over the sloping ground, its load capacity is to be ascertained with due care, keeping in view the lack of confinement away from the slope surface. The degree of confinement will be controlled by the slope angle, type of soil and loading conditions. For this sloping ground situation, lateral pile capacity is more important than vertical load capacity, particularly when the load acts away from the slope. Researchers have been working on pile capacity when the piles are near or on the sloping ground. The present study made an attempt to study the lateral load capacity (LLC) of piles located over sloping ground and the influence of vertical load using both laboratory model tests and numerical modelling (PLAXIS 3D). The study concludes that the LLC of piles increases with the increase in aspect ratio of piles irrespective of single or group and decreases with the slope angle greater than 110. The vertical load on the piles has shown an improvement in LLC of both single and group of piles by 11–7% for the slopes of 00, 110 and 180, the more advantages for higher aspect ratio piles.
