LEAP-ASIA-2019 Centrifuge Test at Kyoto University

The Liquefaction Experiments and Analysis Projects (LEAP) is an international collaborative project that aims to verify, validate, and quantify the uncertainty of numerical liquefaction models. “LEAP-ASIA-2019” is one of the LEAP’s exercises, whose main objectives are to validate the “generalized scaling law” for lateral spreading and to fill the gaps of experiments to complete the dataset obtained as part of the “LEAP-UCD-2017.” Within this project, a total of five models were developed at the geotechnical centrifuge of Kyoto University to simulate the dynamic behavior of a submerged, uniform-density, 20-m-long, 4-m-deep, and 5° sloping deposit of Ottawa F-65 sand. This paper presents the key features of the model preparation and testing process while also examining the applicability of the “generalized scaling law” for centrifuge modeling.
