| Abstract: | This paper presents the effect of initial placement conditions and flooding stress (vertical compressive stress at flooding) on the collapse potential of remoulded loess. Compacted specimens of loess were tested in a one-dimensional consolidometer to study the collapse behaviour. Initial water content, dry unit weight and flooding stress were varied. Collapse potential was found to be dependent on initial water content, initial dry unit weight and flooding stress. Partial collapse was studied by allowing measured increments of water into the specimens. |
