Ultrasonic Pulse Velocity Tests on Compacted Soil

Abstract

In this paper, results of a series of ultrasonic pulse velocity tests on compacted soil were presented and discussed. Ultrasonic pulse velocity tests provide compression and shear wave velocity information that can be used in calculating dynamic elastic moduli such as Young's modulus and shear modulus. From the test results, calculated Poisson's ratio shows a linear relation with the water content in compacted soil, which leads to a linear trend in both P and S wave velocity against water content. Furthermore, presenting plots in bulk density versus wave velocity gives a clearer trend than dry density versus wave velocity.
