www.fast.u-psud.fr3.8 would be obtained, with all velocities merely being changed to shear wave velocities. However, the more common cases of a fluid-solid interface or of two solids separated by a thin film of lubricant would prevent transmission of shear waves across the interface. The case of waves normally incident on a layer sandwiched between two media is the
Guidelines for Estimation of Shear Wave Velocity Profiles
peer.berkeley.edumaintain in situ stresses during testing, and measure the response of a large volume of soil. EPRI [1991)] and Kramer [1996] discuss various geophysical methods for measuring the shear wave velocities of geomaterials. Geophysical methods can be divided into two categories: invasive and non-invasive. Invasive methods require drilling into the ...
