BEHAVIOR OF LATERALLY LOADED PILES IN COHESIVE SOILS

P. Jeyalakshmi, V. Jeyanthi Vineetha

Abstract: Pile foundations are often required to resist lateral loading. Lateral loads come from a variety of sources including wind, earthquakes, waves, and ship impacts. So, it is important to know the lateral load resistance capacity of pile foundation. This requires estimation of ultimate loads based on which safe working loads will be assessed and also estimation of pile deflections to ensure that serviceability aspects are accounted in the design Several methods are available for predicting the ultimate lateral resistance to piles in clay soil. However, these methods often produce significantly different ultimate resistance values. This makes it difficult for practicing engineers to effectively select the appropriate method when designing laterally loaded piles in clay soil. In this paper, lateral load behavior of single piles in clay soil was studied, for different L/D ratio by changing the diameter and length of pile. The analysis was carried out by considering free head pile. The influence of soil type, effect of pile length and pile diameter on the pile response was observed and the results obtained by IS2911Part1 (sec2) were compared with the Broms method. Also deflection and lateral load were calculated for a typical pile for various L/D ratio and their results were presented
