Discrete element model study into effects of particle shape on backfill response to cyclic loading behind an integral bridge abutment

Abstract: The discrete element method, implemented in a modular GPU based framework that supports polyhedral shaped particles (Blaze-DEM), was used to investigate effects of particle shape on backfill response behind integral bridge abutments during temperature-induced displacement cycles. The rate and magnitude of horizontal stress build-up were found to be strongly related to particle sphericity. The stress build-up in particles of high sphericity was gradual and related to densification extending relatively far from … Show more

“…Several experiments with reduced-scale physical models were developed to investigate stresses and deformations of the soil mass behind integral abutment bridges (Tatsuoka et al, 2009;Gabrieli et al, 2015;Zorzi et al, 2017Ravjee et al, 2018;Zadehmohamad and Bazaz, 2019;Al-Qarawi et al, 2020). In these models, soil pressures and wall displacements were obtained from total earth pressure cells and displacement transducers, respectively.…”
