Abstract
Piezoelectric sensors have been widely applied in geotechnical engineering, especially in characterizing soils through measurement of wave velocities. Since mechanical properties of a material are closely associated with wave velocities, piezoelectric sensors provide a reliable and non-destructive method for the determination of soil properties. The following results of recent researches were presented on measuring stiffness of a wide range of soils such as clay, sand and gravel, characterizing anisotropic properties of soil induced by external loading, measuring stiffness of base and subgrade materials in the pavement, determining soil properties in a centrifuge model during the flight of a centrifuge, and understanding wave propagation in granular materials under micro-gravity environment with this technique. It was shown that piezoelectric sensors could be widely and effectively used in researches and practices of geotechnical engineering.
