Abstract

This paper investigated the influence of soil plug effect on the vertical dynamic response of a floating pipe pile based on a three-dimensional continuum model and a fictitious soil pile model. An analytical solution for the vertical dynamic response of a floating pipe pile subjected to an upper dynamic load in the frequency domain is derived using the variable separation method. The three-dimensional characteristics of soil and the coupling dynamic interaction between the pile and the soil are considered comprehensively. Utilizing the developed solution, a parametric analysis is conducted to investigate the impact of various parameters, such as soil plug density, elastic modulus, and Poisson's ratio, on the vertical dynamic response of the pipe pile. The findings and conclusions of the parametric analysis facilitate a better understanding and prediction of the dynamic response of pile foundations across different frequency ranges.

期刊介绍： The journal aims to encourage and enhance the role of mechanics and other disciplines as they relate to earthquake engineering by providing opportunities for the publication of the work of applied mathematicians, engineers and other applied scientists involved in solving problems closely related to the field of earthquake engineering and geotechnical earthquake engineering. Emphasis is placed on new concepts and techniques, but case histories will also be published if they enhance the presentation and understanding of new technical concepts.
