Abstract: A geotechnical centrifuge applies elevated acceleration to small-scale soil models to simulate body forces and stress levels characteristic of full-size soil structures. Since the constitutive behavior of soil is stress level dependent, the centrifuge offers considerable advantage in studying soil structures using models. Geotechnical modeling as a technique for studying difficult civil engineering problems has been increasing in use worldwide since the mid-1980's. However, the technique has been used in England at the Geotechnical Centrifuge Centre of Cambridge University since the late 1960's. This team, under the leadership of Professor Andrew Schofield, is recognized as the world's best and most experienced in geotechnical centrifuge research. The US Army Engineer Waterways Experiment Station (WES) has been doing research on geotechnical centrifuges owned by others in recent years. For this reason, it is important that WES have personnel familiar with the operation and use of geotechnical centrifuges. Training under the guidance of those who have mastered the technology is the only way to obtain the required familiarity and expertise in centrifuge modeling. This report describes details of a training visit by the author at the Geotechnical Centrifuge Centre at Cambridge University. The visit was supported by US Army ACTEDS resources. The objectives of the training visit were to observe and document various aspects of centrifuge modeling including: (A.) facility operation, (B.) experiment design, (C.) model package preparation and instrumentation, (D.) model package mounting and loading, (E.) data acquisition, and (F.) model package assembly. Several experiments were observed and described in relative detail, including experiments in soil dynamics and liquefaction study, an experiment investigating leaning towers on soft foundations, and an experiment investigating migration of hot pollutants through soils. Guidance on facility operation and safety precautions was given by Professor A. N. Schofield and is described in detail in the report.
