Assessment of shear wave velocity variation in compacted soil using pulse transmission techniques
Assessment of shear wave velocity variation in compacted soil using pulse transmission techniques
In this paper, two techniques for benchmarking shear wave velocity in compacted soil during drying are compared. The two techniques considered are both pulse transmission techniques, i.e. bender elements and ultrasonic pulse testing. In past studies, bender elements have been used to monitor the shear wave velocities in soil media whereas ultrasonic pulse tests have been mainly used for determining pulse velocities of rocks because the soil media have higher damping characteristics. While the ultrasonic pulse test system is less established in geotechnical engineering applications compared to bender elements, it is less intrusive as the specimens do not need to be protruded. The results suggest that both pulse transmission systems provide comparable wave responses and thus appropriate for more wide use in geotechnical applications.
