Abstract

There is no doubt that the problem of a laterally loaded pile is an earth pressure analysis problem, involving the flexural rigidity of the pile. During the lateral loading, the earth pressures along the pile may take any value between the state at-rest and the active or the passive state. The current practice, as this is depicted by the various design standards, is the $$p-y$$ method, with the soil to be replaced by an array of parallel springs. This simplification is furthermore accompanied by rough assumptions for the Winkler spring constant. In the present paper, a new analytical method for designing laterally loaded piles is proposed. This method combines the earth pressure theory recently proposed by the author and the theory of elastic beams. The author’s coefficient of earth pressures is a general expression for any soil state between the at-rest state and the active or the passive one, applicable to cohesive-frictional soils and both horizontal and vertical pseudo-static conditions. An analytical expression for the calculation of the required pile movement for the mobilization of the active or passive failure state of soil is also provided. The result of the proposed analysis is complete earth pressure and pile deflection diagrams.
