RESPONSE OF LATERALLY LOADED SINGLE PILE IN SANDY SOIL

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. The lateral capacity of a pile is usually much smaller than the axial capacity and as a result groups of piles are often installed to increase the lateral capacity of the entire foundation system. When vertical or plumb pile groups do not provide sufficient lateral resistance the piles can be battered in order to mobilize some of the higher axial capacity to resist the lateral load. Several methods are available for predicting the ultimate lateral resistance to piles in sandy 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 sandy soil. In this paper, lateral load behavior of single piles in sandy soil was studied, for different L/D ratio by changing the diameter and length of pile. The analysis was carried out considering long 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) and Matlock & Reese were presented.
