APPLICATION OF CENTRIFUGAL MODELLING TO CONE PENETROMETER TECHNOLOGY

Keith A. Ferguson, H.Y. Ko

Open publisher page 1 citations

Abstract

The quasi-static cone penetrometer has been successfully modelled in the centrifuge at the University of Colorado. This model program demonstrated significant advantages for prototype calibration over conventional procedures using large triaxial calibration chambers. Four different soils (sands) were tested and empirical relationships between cone penetration resistance and fundamental soil properties such as relative density, friction angle and soil modulus were established. Results of the centrifuge program were then compared to current state-of-practice procedures for predicting fundamental soil properties, foundation settlements, and liquefaction potential. The number of the covering abstract of the symposium is IRRD 286058. (TRRL)
