Seismic Downhole TestingPurpose of the seismic down-hole tests is the determination of the compressive and shear velocity of the soil layers in the area, as well as the determination of the dynamic parameters of the soil.We prefer to Borehole Method Wave Velocity Test. If Cross-Hole Method for Wave Velocity Test ,three boreholes will be needed, in according to ASTM D4428/D4428M-00.Test report should include Recorded Wave Curve, Velocity of Compression Wave and Shear Wave. The report should also include Shear Modulus, Elastic Modulus, Poisson’s Ratio and Dynamic Stiffness of soil layers in low-strain.
