Abstract

This case study describes the design, and construction of an earth dam built on recently sedimented tailings consisting of low strength, low plasticity silt/clay, and variably silty sand. The tailings were encountered within the construction limits of Cell 7 at the 4 km(2) Loxahatchee (L-8) Reservoir in western Palm Beach County, Florida. Fully coupled steady state and transient seepage models with slope stability analyses were performed for operational and rapid drawdown conditions, respectively, using both limit equilibrium methods (LEM) and finite element stress-based modeling (FESBM) techniques. In addition, stability calculations utilizing fully coupled stress/pore pressure analysis were performed to analyze rapid drawdown stability during drawdown. (C) 2012 Elsevier B.V.
