A New Boundary Stress Transducer for Small Soil Models in the Centrifuge



The need to obtain reliable boundary stress measurements in centrifugal models of reinforced earth retaining walls has led to the development of a new form of boundary stress transducer. A rectangular sensitive face 100 mm long by 10 mm wide has been chosen to capture sufficient soil grains to give a representative soil pressure. Calibrations of the transducers under a layer of sand in the centrifuge were in good agreement with the deadweight calibrations. When used in a series of centrifuge model tests, the new transducers performed reliably in an environment that was anticipated to have a relatively large stress gradient.
