摘要
采用动力文克尔地基梁模型，首先求出层状土中有限长桩的通解，在此基础上导出了桩单元复刚度矩阵，提出了计算层状土中单桩动力阻抗的方法．本文成果可以用来研究层状土中群桩的动力阻抗、桩－土运动相互作用等问题．
The BeamonDynamicWinklerFoundation(BDWF) model is used to derive the element complex stiffness matrix of a single pile based on the general solution of a pile with the finite length obtained in this paper.The method for calculation of the dynamic impedances of single piles is developed.The result obtained in this paper can be used to study the problems such as the dynamic impedances of pile groups,kinematic pilesoil interaction and so on.
