| 摘 要： | 根据能量守恒原则,利用桩的水平静载变形曲线求取分层土等效为均匀土层的参数;采用Winkler地基梁模型计算了分层土中桩的水平动刚度,并针对Winkler地基梁模型计算动力问题的缺陷提出修正建议。本文中提出的方法也可用于分层土中单桩弯曲、垂直动刚度的计算。

| 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. |
