Abstract

To evaluate the importance of small-strain shear modulus in geotechnical engineering applications, different techniques such as bender element, resonant column apparatus and on-sample LVDTs are being used by the researchers. This paper presents the results obtained from resonant column tests, bender element tests and on-sample LVDT for sandy soil, to emphasise the significance of on-sample LVDT for the measurements of small-strain properties, in contrast to the resonant column and bender element tests. Results indicated that the on-sample LVDT is successful and useful for the evaluation of dynamic soil properties at small strain.
