ABSTRACT
In recent decades, the numerical method is widely used in predictions of geotechnical phenomena and evaluations on geo-hazards. However, it has not proved its preciseness and applicability on reality. As that consequence, many centrifuge modelling laboratories has been participating the international collaboration projects, the Liquefaction Experiments and Analysis Projects (LEAP), which aims to calibrate and validate the centrifuge modelling and numerical modelling. In LEAP 2017, the goals are to perform the sufficient number of experiments to characterize the median responses and its uncertainty of a specific saturated sandy slope ground under specified input motions. The main input motion is a tapered sine wave. In this study, two input motions were conducted in one model which follow the experiment procedures required by LEAP 2017. The maintaining input motions are sine wave motion and negative sine wave motion, respectively, to discuss the interactions between the sloping model and the waveforms.
