Dynamic behaviour of rigidly-capped pile groups of vertical and rocking oscillations

Abstract

The behaviours of soil layers in a different depth are presented mainly. The pile group and the surrounding soil are discretized into horizontal layers, which meet a plane strain assumption. By means of that the single pile dynamic impedance is developed using a transfer matrix method, the pile -to-pile dynamic interaction factor is derived. Then, the paper introduces the dynamic impedances of rigidly-capped pile groups with due consideration to pile-soil-pile interaction for vertical and rocking oscillations. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
