The most common function of piles is to transmit foundation loads which cannot be adequately supported at a certain level down to a depth at which adequate support is available. The classification of piles in terms of loading may be considered as vertically or laterally loaded. The laterally loaded pile is a structural member which sustains transverse loads in a similar way a beam does. The lateral force that the pile foundations is subjected to may be induced by earthquake, water waves, moving vessels, wind force, and lateral earth pressure, etc. Early techniques for analyzing laterally loaded pile foundations completely ignored the soil resistance; the ends of the piles were treated as either pinned or fixed, and the problem became strictly an exercise in structural mechanics. It was generally recognized that these techniques were extremely conservative. The increase in quantity and size of civil engineering works nowadays has thrown large economic pressure for a more precise knowledge of the behavior of pile foundations subjected to lateral load.
