Settlement of Uranium Mill Tailings Piles: A Comparison of Analysis Techniques
Two empirical methods of settlement analysis (Terzaghi's theory and a simplified version of the Fredlund-Morgenstern two-stress-state approach) were compared to the computer code TRUNC, a modified version of the TRUST code for variably saturated flow in deformable porous media. The three methods were used to predict settlement of a 12.2-m-deep pile of tailings slimes with a drain at the bottom. The simpler, empirical methods of settlement analysis were just as effective as TRUNC in predicting total settlement. Terzaghi's theory, as applied, overestimated the time of settlement under saturated conditions (170 days versus 140 days predicted by TRUNC) because it did not account for gravitational gradients. No empirical or analytical means were available to predict the time of settlement under partially saturated conditions. If the magnitude of partially saturated settlement is considered significant, then the time over which it occurs will most likely be the deciding factor in determining when to place the cover on the tailings pile.
