Ultimate Lateral Load of a Pile Cohesive Soil Under Static Loading
Dileep M. Dewaikar, Poonam A. Patil
In this paper, the ultimate lateral resistance of a long, flexible, unrestrained vertical pile in a cohesive soil is computed under static loading condition using p-y curves. A simple and improved method for the construction of hyperbolic p-y curves for a cohesive soil is proposed for static loading conditions. An iterative analysis is employed with secant modulus approach, using a matrix method known as moment area method developed by Sawant and Dewaikar. The load-ground line displacement relationship is obtained for different load eccentricities using p-y curves developed by Matlock, Georgiadis, et al. and the proposed hyperbolic p-y curves for different eccentricity ratios. These values are compared with the values computed from model test performed by Rao et al. and with the limit equilibrium solution give by Broms. The comparison shows that, the results obtained using hyperbolic p-y curves shows a better agreement with the model test data with the maximum difference within 15% using other methods; whereas Broms’ limit equilibrium solution shows some agreement with the results based on Matlock’s p-y curves.
