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: The results of the experiments show significant differences between each other, but the responses show a significant correlation, R2 ~ 0.7-0.8, to the known variation of the input parameters as mentioned in this paper.

TL;DR: The specifications developed by and distributed to all of the centrifuge test facilities involved in LEAP-UCD-2017 were described in this article, which consisted of a submerged medium dense clean sand with a 5-degree slope subjected to 1 Hz ramped sine wave base motion.

TL;DR: A crosshole type shear wave velocity tomography testing system has been developed, and the distribution of maximum shear modulus in sand layers could be evaluated in the centrifuge.

TL;DR: In this article, the effect of rockfill material degradation on the seismic response of dam models was investigated and the results indicated that an irregular stiff foundation is believed to affect the attenuation characteristics of motion.
