Design of landslide stabilizing piles by numerical techniques and other methods

Because of the large bending moments to which landslide stabilizing piles are subjected, drilled shafts used to enhance slope stability are generally reinforced with massive steel I-beams or reinforcement cages, and often incorporates several rows of tiebacks. A case history will be presented in which a minimum static Factor of Safety of 1.5 was required for the slope stabilization by the permitting agency. The application of a Factor of Safety requirement is not as straight forward as it may appear, and designs by various consultants often differ significantly for similar slopes. To avoid this type of problem stabilizing piles can be designed from both a geotechnical and structural perspective by the strength reduction method using numerical programs such as FLAC or PLAXIS. These type of numerical approach will be compared to various traditional methodologies often used by consultants.


Dr. Daniel Pradel, P.E., G.E., D.GE., F. ASCE — The Ohio State University

Dr. Daniel Pradel is a Professor at the Ohio State University. Previously he was Vice-President at Shannon & Wilson in Glendale, California, and an Adjunct Professor at the University of California, Los Angeles (UCLA). Daniel is a professional engineer registered in California, Nevada, Hawaii, Utah and Switzerland. He has worked on the geotechnical design of numerous landslide stabilizations, deep excavations, MSE walls, transportation systems, and dams worldwide, and has published over 30 papers on earthquake induced landslides, seismic site response, seismic compression, slope instability and the stabilization of slopes using drilled shafts. Many of his publications involve numerical modeling for static and dynamic response. Daniel is an Associate Editor of the ASCE Journal of Geotechnical Engineering, a Diplomate of the Academy of Geo-Professionals and a Fellow of ASCE. He is active in numerous committees of the DFI and ASCE’s GeoInstitute.
