【Abstract】 According to the principle of conservation of energy, lateral impedance of piles in layered soil is presented on the basis of the "Beam_on_Winkler_foundation". Equivalent parameters of the layered soil as homogeneous soil are calculated by deflection of the pile under lateral static loads. In view of the defects of using the "Beam_on_Winkler_foundation", some suggestions are given to solve some dynamic problems. In addition, the method proposed in this paper can also be used to calculate the bending impedance and vertical impedance of single piles in the layered soil.更多还原
