T-bar testing procedures and bearing factors are now well established, enabling assessment of sample shear strength profiles from penetration measurements. However, there is limited information in the literature about the technological aspects of small scale T-bar devices and how factors independent of the soil sample may affect measurements of the penetration resistance and hence shear strength. This paper investi-gates and evaluates a variety of factors that may affect the measurement of penetration resistance in normally consolidated kaolin clay. The objective of the study described has been to provide recommendations for fu-ture penetrometer testing at model scale, specifically in a centrifuge but also for other laboratory testing such as in a calibration chamber.
