Horizontally Mounted Bender Elements for Measuring Shear Modulus in Soaked Sand Specimen

Article Preview

Abstract:

New horizontally mounted bender element devices capable of high-quality transmission and reception of horizontally propagated shear waves polarized in orthogonal planes across the mid-height of a sand specimen are described. Mounting of these bender elements is on the membrane, attaching on the side wall of the reactor container. This technique is suitable for use on samples down to 80 mm length. The effective fabrication procedures that have been developed are described. The instrumentation systems used to drive and receive signals are outlined, and estimates of the magnitude of the shear strains developed by the bender elements and the accuracy with which shear wave velocities can be determined are discussed. The sand specimen is treated by the solution then its strength is developed. These new bender elements enable shear modulus to be measured before, during and after the treatment.
