Trends and characteristics of the LEAP 2020 Soil-Retaining Wall response

抄録

The 2020 Liquefaction Experiments and Analysis Projects (LEAP) included 23 centrifuge tests of a saturated Ottawa sand deposit supported by a cantilever (rigid) sheet-pile quay wall. In this paper, a Gaussian process regression is used to assess the complex non-linear relationship between the backfill lateral displacements and the input motion initial experimental conditions. The conducted analyses showed that the LEAP-2020 experimental results are consistent and shed light on a number of salient characteristics and trends of the soil lateral displacements and interaction with the retaining wall during liquefaction.
