Abstract
The present paper describes a new triaxial apparatus which allows the measurement of low strain stiffness by means of both bender elements and resonant column test. In a previous paper Squeglia et al. (2009) described the innovative use of bender elements as receivers for the measurement of shear wave velocity. The proposed technique is synthetically described with the further development of apparatus which allow to perform resonant column test during a triaxial test. Since the apparatus has not been designed as a resonant column device, some critical points have been dealt with. Some tests have been dedicated to solve the problem of apparatus calibration, in particular it was not clear which type of restraint was introduced by some mechanical details concerning the ram for application of axial load. After calibration, some results have been presented. Tests carried out with the new apparatus have been compared with results of tests carried out with a Drnevich type resonant column apparatus showing a good agreement.
