Horizontally Mounted Bender Elements for Measuring Anisotropic Shear Moduli in Triaxial Clay Specimens

摘要

Novel horizontally mounted bender element de- vices capable of high-quality transmission and reception of hori- zontally propagated shear waves polarized in orthogonal planes across the mid-height of a triaxial clay specimen are described. Mounting of these mini benders, in a T-shaped configuration, is in The pads of a radial strain belt on 100 mm diameter triaxial samples, Or alternatively as bender probes(similar in concept to mid-height Pore pressure porbes)suitable for use on triaxial samples down to 38 mm diameter. This latter type may also be used in bench-top tests or on site.
