TL;DR: In this article, the propagation and attenuation characteristics of various source generated vibrations were investigated by analyzing particle motions, and the measured attenuation data matched well with the predicted data when using the suggested geometric damping coefficient, and estimated soil damping ratios were quite reasonable taking soil type of the site and experiencing strain level into consideration.

TL;DR: In this paper, the propagation and attenuation characteristics of vibration were investigated by measuring the various ground vibrations induced by train loading, blasting, friction pile driving, and hydraulic hammer compaction.

TL;DR: The first large scale geotechnical centrifuge in Korea has recently been developed at KAIST under the Korea Construction Engineering Development (KOCED) Collaboratory program as discussed by the authors.

TL;DR: In this article, the authors proposed a design method considering interaction effects for a piled raft foundation, where the raft is considered as a plate supported by a group of piles and soil, and the ultimate load capacity of the pile group is taken into account in calculating the settlement when the foundation is subjected to a large vertical external load.

TL;DR: In this paper, a large number of dynamic centrifuge tests and corresponding seismic response analyses were performed to evaluate the dynamic performance of a newly constructed ESB model container and to shed light on the range of testable soil conditions.
