Deendayal Department of Civil Engineering, National Institute of Technology, Tiruchirapalli India ABSTRACT In the off-shore structure, the lateral load, vertical load, and the overturning moment are very large compared to those found in onshore structures. Also, there is a frequently major cyclic component of both vertical and horizontal loads. In the present study, the numerical analysis has been carried out by using PLAXIS 2D. The analyses were carried out on single model pile under cyclic loading to determine the behavior of the pile. A single pile of embedment length to diameter ratio (L/D) of 16, 25 and 33 were located on the horizontal ground surface and slope angle of 1V:1.5, 1V:2H and 1V:3H was subjected to cyclic loading. From the analysis, the acceleration, displacement and bending moment of the pile under each case was studied. From the study, it is very clear that as L/D ratio increases, the acceleration, maximum displacement and bending moment are reduced.

INTRODUCTION Offshore structures, namely, oil drilling platforms, jetties, tension leg platforms etc. are mostly supported on pile foundations. Apart from the usual super structure load like dead load, live load, these piles are subjected to continuous lateral cyclic loading resulting from ocean waves. Considerable investigations have already been carried out in the related field of research. Matlock and Reese [1] made the first attempts to understand the behaviour of laterally loaded piles. They have developed the solutions for soil reaction, bending moments and deflections for both short and long piles. Broms [2] developed a solution for the ultimate lateral resistance of the pile assuming the distribution of lateral pile soil pressure and considering the statics of the problem. Singh and Verma [3] conducted large-scale model tests in sand under controlled density. Lateral load tests were conducted on single pile and pile groups. From the results, it was observed that the load deflection curves were found to be
