shear wave velocity and penetration resistance using MASW technique T.P.Thaker & K.S.Rao Department of Civil Engineering, Indian Institute of Technology Delhi, New Delhi-110016, Delhi, India ABSTRACT Prediction of ground shaking response at soil sites requires knowledge of the soil, expressed in terms of shear wave
and 32 m depth. The velocity (ν) of a shear wave is equal to the square root of the ratio of shear modulus (G), a constant of the medium, to density (ρ) of the medium, ν = Square root of√G/ρ. Both shear (transverse) and compressional (longitudinal) waves are transmitted in bulk matter. Shear wave velocity (VS) is a valuable indicator of the dynamic properties of soil and rock because of its relationship with Gmax, given by Equation (1.1): Gmax= ρ ·VS 2(1.1) where soil density (ρ) is the total unit weight of the soil divided by gravity (9.81 m/sec2or 32.2 ft/sec2).
A simplified procedure using shear-wave velocity measurements for evaluating the liquefaction resistance of soils is presented. The procedure was developed in cooperation with industry, researchers, and practitioners and evolved from workshops in 1996 and 1998.

Purpose: To assess the variability of shear wave velocity (SWV) from acoustic radiation force impulse (ARFI) elastography at various depths using different frequencies. Materials and methods: ARFI elastography of the elasticity phantom and normal liver was performed at different depths (2-5 cm) with convex (1-4 MHz) and linear (4-9 MHz) probes. The velocity of the shear wave is about half of the velocity of the compression wave.

This method tests a much larger volume of the subgrade compared to borehole measurements using the down-hole methods. Our equipment is capable of determining the average shear wave velocity over distances up to 300 feet and down to depths of 100 feet. No permits are required to use this test method, since it is non-invasive and non-destructive.
