Discussion on 'Required unfactored geosynthetic strength of three-dimensional reinforced soil structures comprised of cohesive backfills' by Y. Chen et al., (2018) doi.org/10.1016/j.geotexmem.2018.08.004

摘要

The authors of the paper "Required unfactored geosynthetic strength of three-dimensional reinforced soil structures comprised of cohesive backfills" (Chen et al., 2018) have presented an interesting study in which limit analysis (LA) upper bound solutions for 3D failure mechanisms in reinforced cohesive backfills are provided for the first time. The discusser would like to comment on four issues related to the paper: (1) no consideration for the onset of cracks in the slopes (2) use of the presented solutions for forensic analyses (3) underestimation of the level of required reinforcement (4) unsuitability of the presented solutions for design purposes.
