Synopsis

This open access book presents work collected through the Liquefaction Experiments and Analysis Projects (LEAP) in 2019 (LEAP-ASIA-2019) following the LEAP-UCD-2017 whose results have been published as a first volume. In addition to the research targets set in the previous one, such as the repeatability, variability, and sensitivity of lateral spreading on mildly sloping liquefiable sand, this volume includes research efforts to validate the generalized scaling law (hereafter “GSL”) for the identical prototype with the one employed in UCD-2017. In LEAP-ASIA-2019, 10 institutes around the world conducted 23 tests in total. It was the first multi-institutional attempts to investigate the validity of the generalized scaling law for the saturated sandy sloping deposit with wide range of initial conditions. The experimental data provided a unique basis for assessing the capabilities of six different simulation platforms for numerical simulation of soil liquefaction. The results of the experiments and the numerical simulations are presented and discussed in papers submitted by the project participants.

In 2003, he obtained the doctor of Engineering from Kyoto University of with the dissertation title “Application of performance-based seismic design concept for caisson-type quay walls.” In 1995, he started his career in earthquake engineering as a researcher at the Port and Harbour Research Institute, Ministry of Transport, Japan. He moved to Hiroshima University as an associate professor in 2005, and joined the Faculty of Societal Safety Sciences, Kansai University, as an professor in 2017. He has been working on not only engineering issues such as seismic design and maintenance of structures, but also educational issues such as how to tell children about disasters by using picture books and kid’s songs.

 

Kyohei Ueda

Dr. Kyohei Ueda is an Associate Professor at the Disaster Prevention Research Institute (DPRI), Kyoto University, Japan. He received his bachelor's (2005) and master's (2007) degrees in Civil Engineering from Kyoto University. In 2010, he obtained his Ph.D. from Kyoto University with a dissertation titled "Finite Strain Formulation of a Strain Space Multiple Mechanism Model for Granular Materials and Its Application." After working as a researcher at the Port and Airport Research Institute (2010-2011) and the Railway Technical Research Institute (2012-2014), he joined the DPRI as an assistant professor in 2015 and was promoted to associate professor in 2022. His research interests include geotechnical earthquake engineering and soil dynamics, and he has been studying subjects concerning numerical and centrifuge modeling on the complex seismic behavior (e.g., liquefaction) of soil-structure systems.
