Pile foundations are often subjected to lateral loads due to earth pressure, earthquake loading, wave force and wind forces etc. The pile design shall ensure estimation of ultimate pile load carrying capacity and allowable pile deflection and thus both strength and serviceability aspects are considered. In the present study, lateral load behavior of single pile in cohesionless soils is attempted for various soil types viz., loose sand, medium sand and dense sand. The subgrade modulus of each soil type is assumed based on approximate values available in the literature. The pile soil behavior is observed for both dry and submerged conditions. The analysis is carried out considering fixed head pile and floating tip at the base. Parametric studies have been carried out to evaluate the influence of pile and soil properties on the flexural response of piles. The significance of soil type in altering the pile deflection and flexural response is discussed. Also deflection and moment coefficients are evaluated for a typical pile length for various soil types. Various methods available in pile-soil interaction analysis are discussed. A computer program is developed using MATLAB by considering modulus of subgrade reaction approach. Finite difference technique is chosen for the above analysis. The output of computer program is validated with the available benchmark solutions in literature.
