COLLAPSE OF GEOGRID-REINFORCED RETAINING STRUCTURE. DISCUSSION AND CLOSURE

A discussion of a paper with the aforementioned title by Leonards, Frost, and Bray, published in this journal (Volume 8, Number 4, November 1994), is presented. Discusser Day commends the authors on reaching similar conclusions to his own regarding wall collapse related to a large reduction in shear strength of compacted clay backfill as it becomes wet. Day adds that the slope-softening process may also be responsible for the collapse of the geogrid-reinforced retaining structure described by the authors. The discusser performed constant-stress direct shear tests to study the amount of slope deformation due to slope softening. Discussion is followed by closure from the authors.
