Engineering Insights into Laterally Loaded Pile Foundation on Sloping Terrain: A Comprehensive Assessment of Behavioural Parameters and Practical Design Implications
摘要
There are many situations in hilly regions where building or other superstructures have to be provided near a slope. It is always preferable to adopt deep foundations to transmit the load from the superstructure to a depth well below the slip surface. This is essential to the slope’s stability. The presence of a slope on one side adversely reduces the passive resistance offered by the soil. Hence, pile foundations installed in sloping ground require a proper assessment of soil-pile interaction. The response of pile foundation in the level ground conditions is well established; however, the effect of nearby slope on the pile response is not fully explored. Against this backdrop, this paper reviews the research work carried out to evaluate the effect of sloping ground on the response of laterally loaded piles. Some significant works carried out on various aspects of pile foundations in sloping ground are reviewed. Following a quick glance through the corresponding literature, the works reported by various researchers are described under three parts: experimental, experimental-cum-numerical and numerical studies. Based on the summarized findings emerging from the literature review, a critical appraisal is presented, and gaps are identified.
