Abstract: Based on principle of minimum potential energy, the government equations of single pile’s load-settlement response are established. The solution of the pile-soil system obtained by using analytical form for soils displacement and difference scheme for pile. The effect of soil’s nonlinearity on settlement response is considered by assuming that soil is linearly elastic-perfectly plastic. And the corresponding computer method is proposed. Then a program is developed based on Maple software. According to the numerical examples, the influences of soil parameters and slenderness ratio of pile on the settlement response are studied. The proposed method is used to analyze a full-scale static loading test pile; and the predictions are in reasonable agreement with the measurements.

Key words: single pile, Gibson soils, nonlinear analysis, settlement, principle of minimum potential energy, parametric analysis
