| Abstract: | A simple method is developed for computing the horizontal impedance of single pile in soil layer with variable properties. Using this method, the soil layer with variable properties is turned into an equivalent homogeneous soil layer, so the horizontal impedance of single pile in soil layer with variable properties can be calculated easily under the condition of the equivalent homogeneous soil layer. A numerical example is given. The results indicate that the method presented in this paper is practicable if the weighted function is selected properly. |
