Abstract

In order to satisfy the demand of high precision of shear wave velocity measurement in soil mechanics and geotechnical engineering

a set of piezoelectric bender element system was developed based on virtual instrument technology.The system mainly consists of piezoelectric bender elements

power amplifier

charge amplifier

and computer

et al.The measurement software was programmed by LabVIEW

and the functions of signal generator and data acquisition were realized by the sound card.The system has the advantage of cost-effective

and high measurement efficiency.It has been successfully applied to measure the shear wave velocity of sand.
