DYNAMIC RESPONSE OF SINGLE PILE LOCATED IN SOFT CLAY UNDERLAY BY SAND

Abstract

Piles have been extensively used for supporting axial loads and lateral loads for variety of
structures including high rise buildings, transmission towers, power stations, offshore structures and highway
and railway structures. Pile foundations are subjected to lateral loading due to wind action, wave action,
earthquake and impact of ships in dock and harbour structures. In such cases, studying the behavior of pile
foundation due dynamic loading is essential. Compare to field tests, the numerical modeling is an economical
way to analyze the response of piles. This paper presents the dynamic response of a single concrete pile of 0.4m
diameter, 11.5m length located in soft clay underlay by sand subjected to static vertical load as well as ground
acceleration simultaneously. Finite element software PLAXIS 2D is used to analyze the pile. From the analysis,
the deformation and acceleration behaviour of pile with respect to time has been studied.
