Farzad Daliri . The influence of dessication and stress history on monotonic and cyclic shear response of thickened gold tailings . In thickened tailings technology, tailings are dewatered to the point where they exhibit a yield stress such that they form gently sloping stacks during deposition. Post-deposition, these tailings may densify due to settling, desiccation, and drainage. Fresh ...

Slurried soils or tailings are often deposited in layers that undergo complex stress paths in terms of desiccation and loading, as a given layer may undergo variable degrees of desiccation before burial by subsequent layers, which has implications for geotechnical stability and geo-environmental performance.

مقاله The influence of desiccation and unsaturated

Since the dewatered tailings are normally deposited sub-aerially in tailings storage facilities, the volume change, hydraulic conductivity and shear strength behaviour of the deposited tailings are a function of unsaturated soil properties and fall in the realm of unsaturated soil mechanics. It is found that there is a stress history in cyclic deposition of dewatered tailings, which can be ...
