520			_aGeotechnical Engineers face a constant challenge when it comes to well foundation systems. Predicting the lateral response of the Well foundation is one of the most difficult tasks. Although a lot of study has been done to predict the exact lateral response of a pile, predicting the lateral response of a well foundation is still complicated. For the prediction of lateral response, parameters such as size, shape, and in-situ properties of the soil around the foundation playing a vital role. By using this parameter, with the help of numerical tools such as LPILE, FB-MultiPier, and others, many researches have been effective in forecasting the lateral reaction of pile foundations. Even though the approach was considered satisfactory, the results are insufficient for large diameter foundations and well foundations. Furthermore, selecting an appropriate geotechnical model in the numerical tool is problematic. For most foundations, the subgrade response approach is a regularly used method for estimating lateral displacement. For estimating the modulus of subgrade reaction, several formulae have been developed. Vesic’s equation is the most often used. However, it has the drawback of underestimating the lateral capacity of larger diameter Pile and Well foundations. To overcome this modified Winkler’s equation is proposed. With the help of the numerical analytic software FB-MultiPier, an extensive comparison of Vesic’s and Modified Winkler’s Equations for two different length to diameter ratios (L/D) ratios is carried out and in this work.
