Abstract

Abstract: The Liquefaction Experiments and Analysis Projects (LEAP) is an international effort to produce a set of high quality test data and to then use it in a validation exercise of existing computational models and simulation procedures for soil liquefaction analysis. A validation effort (LEAP-GWU 2015) was undertaken using a benchmark centrifuge model of a sloping deposit tested in a rigid-wall container. This article presents and discusses the shear stress-strain responses and effective stress paths of the LEAP-GW 2015 centrifuge tests and numerical predictions (including an assessment of the effects of the rigid boundaries). Abstract : Highlights: Stress-strain responses of centrifuge sloping sandy deposits were analyzed. Stress-strain responses of associated numerical predictions were analyzed. The effects of rigid boundaries on soil response were assessed.
