DESIGN OF DRILLED SHAFTS TO ENHANCE SLOPE STABILITY (2010)
This paper describes a numerical approach for the design of drilled shafts to reinforce slopes. The approach uses the program FLAC and the strength reduction method to predict the Factor of Safety of the improved slope. The method successfully predicted the maximum demands (shear force and bending moments) necessary for the structural design of stabilizing piles. The method also successfully predicted the critical mode of failure and slope stability Factors of Safety for piles with a plastic bending moment.
