FIELD DETERMINATION OF ANISOTROPY AND THE COEFFICIENT OF LATERAL EARTH PRESSURE

Particulate materials such as soils and aggregates, whether natural or manufactured, are inherently anisotropic with respect to stiffness and strength properties. Anisotropic mechanical properties are not routinely assessed, yet differences in material properties can influence design-based calculations. The paper presents a methodology for assessing anisotropic shear properties of particulate materials. The method is based upon the measurement of seismic shear wave velocities via improved and extended crosshole testing techniques. Measurements completed at a number of test sites have demonstrated the ability of the methodology to assess the anisotropic shear modulus of particulate materials. A promising application of the measurements is in situ assessment of the coefficient of lateral earth pressure.
