摘要: A formulation for the analysis of pile groups in layered semi-infinite media is presented. The based on introduction a soil flexibility matrix as well dynamic stiffness and matrices piles to relate discretized uniform forces corresponding displacements at pile-soil interface. Pile group analyses revealed that behavior highly frequency dependent result wave interferences occurring between various group. Large values stiffnesses large magnification factors essentially follow low components ground motion. rotational component negligible typical dimensions foundation.
