An Experimental Study on External Forces on Pile Group from Flowing Liquefied Soil
The purpose of this study is to investigate the fundamental characteristics of the external forces on pile group from the flowing liquefied soil with shaking table tests under 30 G centrifuge condition, where a model of pile group was installed in flowing liquefied soil, were carried out. The pile group consists of 9 model piles. The following result was obtained from the experimental study. In the case when the model ground was not liquefied or partially liquefied, elastic force related with displacement of the ground is dominant, while in the case when the ground is perfectly liquefied, the viscous force related with the flow velocity of the ground is dominant. The viscous force is much larger than the elastic force.
