This report describes studies conducted for Phase II of the project Restraining Post-Liquefaction Flow Deformations. To provide a context for this report, the background of the project will be reviewed briefly and some key findings from the first phase will be presented. In Phase I of the project, studies were focused on the use of piles to restrain flow deformations. This topic was of considerable interest to the US Army Corps of Engineers because pile-nailing of the upstream slope of Sardis Dam in Mississippi was being considered as an option for restraining sliding of the slope on a potentially liquefiable thin layer in the foundation. The key factors controlling the feasibility and cost of pile installations to restrain flow deformations are pile length and spacing, stiffness and strength of un liquefied soils surrounding the piles, residual strength of liquefied soils, the geometry of the structure, and the intensity of shaking after liquefaction has occurred.
