A simple numerical model is presented for handling both linear and nonlinear soil-pile interactions. In the present method, the diagonal terms of the exact soil impedance matrix define the elastic characteristics of Winkler side soil springs. When its off-diagonal terms are described as a function of the pile's active length, they were found less dependent on the other secondary factors. Despite the simplification, the proposed nonlinear soil model can reproduce piles's behaviors computed by more rigorous finite element methods.
