BEHAVIOUR OF A PILE AND PILE GROUP IN SANDY SOIL SLOPES UNDER THE COMBINED LOADING

Abstract

The growth of infrastructure development globally has led to the construction of high-end structures such as tall buildings, long-span bridges, transmission lines, and retaining walls. Pile foundations are a widely utilized solution. They also endure substantial lateral forces, such as those induced by wind, waves, seismic activity such as earthquakes, and traffic impacts. Many of these structures are situated in proximity to excavated or fill slopes, adding a layer of complexity to their foundation design. However, there is a notable gap in comprehensive research on single pile and group piles located on/near the soil slopes under combined loading conditions. The existing literatures mainly focuses on the behaviour of pile groups under lateral loading in sand and soft clay conditions. Only Deendayal (2017) briefly examined the behaviour of a 3x3 pile group on sloping ground, but the study did not specifically address the effect of varying slope angles on the response of the pile group.
