Model Testing in Geomechanics Centrifuge and Hydraulic Gradient Approaches


The lecture will present some background to the difficulties of model testing in geotechnical engineering and will describe two methods to overcome these problems: centrifuge modeling and application of hydraulic gradient. The latter method is less known, and so two studies using this approach, carried out at the Technion, will be discussed more fully the static, axial capacity of driven piles in sand, and the seismic response of piles in sand. The latter has been performed on small models in a laminar model box fixed to a shaking table. Details of the experimental setup, and some test results will be presented.

Short Biography

Sam Frydman was born and educated in Australia, receiving his first degree - B.E (Civil), from Melbourne University. He worked for CSIRO research organization and then went to Israel, where he received his MSc and PhD at the Technion Israel Institute of Technology. He is now Professor of Civil Engineering at the Technion. He has headed the geotechnical group there for many years, and has served as Head of the Structural Engineering and Building Management Department. He is a past President of the Israel Geotechnical Society, a member of editorial boards of a number of international publications, and consults on engineering projects. His research interests include constitutive and physical modeling in geomechanics, unsaturated and swelling soils, and geotechnical aspects of earthquake engineering. He has spent sabbatical periods at Cambridge and Oxford Universities and Imperial College in England, Melbourne and Monash Universities in Australia, University of Auckland in N.Z., and U. of Mass, and MIT in USA.
