Field and laboratory measurements of shear wave velocity in unsaturated soils

Shear wave velocity measurements in soil are important for assigning site profiles to seismic classes and calculating other dynamic properties. The cone penetration test (SCPT) is commonly used determine shear the field. In laboratory, bender elements provide an easy means measure of specimens from discrete depths. this study, obtained unsaturated field on samples laboratory under similar stress conditions were analyzed compared. Additionally, influence seasonal changes behavior was investigated. Comparisons velocities favorable moisture conditions. However, results showed that as degree saturation increases suction decreases can decrease significantly.
