The presented research work had a primary goal of developing a reliable and representative design method that accounts for the effect of the soil and pile properties and pile spacing on the performance of pile-stabilized slopes based on the soil-pile-interaction. The proposed design approach was also compiled into a computer program for the analysis of pile-stabilized slopes. The strain wedge (SW) model technique developed by Norris (1986), Ashour et al. (1998), and Ashour and Ardalan (2012-1) for laterally loaded piles (long, intermediate, and short piles) based on the soil-structure interaction was modified to analyze the behavior of piles used to improve slope stability. The computer software (PSSLOPE-M), which was written in Visual Basic and FORTRAN, was developed to implement the presented technique for pile-stabilized slopes, including the slope stability analysis (with no piles) using the Modified Bishop Method. The computer software is available from the researcher, Dr. Mohamed Ashour at ashouruah@gmail.com. Click Here to download copy of project report
