Road Embankment and Slope Stabilization
This report and the accompanying software are part of efforts to improve the characterization and analysis of pilestabilized slopes using one or two rows of driven piles. A combination of the limit equilibrium analysis and strain wedge (SW) model technique is employed to assess the stability of vulnerable slopes before and after using driven piles to improve the slope stability. This report focuses on the entry of input data, interpretation of the output results, and description of the employed technique. In addition to a comparison study with a full-scale load test, the finite element (FE) analysis using a general-purpose FE package, PLAXIS, is performed to verify the results. The characterization of lateral load induced by slipping mass of soils can be accomplished using the modified SW model technique. The SW model for laterally loaded pile behavior is a new predictive method (recommended as an alternative method by American Association of State Highway Officials (AASHTO) (2007)) that relates the stress-strain behavioral of soil in the developing three dimensional passive wedge in front of the pile (denoted as the strain wedge) under lateral load to the one dimensional beam-on-elastic foundation parameters.
