Abstract: Shear wave propagation in soil is a physical phenomenon and has been used widely for monitoring and seismic property assess-ment in geotechnical engineering. Shear wave velocity Vs and small-strain shear modulus G0 are the key parameters in … The shear wave velocity is linked analytically to the shear modulus and the density of the soil. Furthermore, it has been shown it is a function of the void ratio and the current state of stress. It has been measured at the three sites by using Down hole method.

Test, Cone Penetration Test) and shear wave velocity measurements. Shear wave velocity tests are increasingly being used to assess a wider range of soil properties in-cluding strength.

An experiment was carried out to develop a technique to measure shear wave velocity simultaneously with the standard penetration test popular in soil engineering. In the standard penetration test an impact at the bottom of a borehole is produced by weight dropping and may be expected to generate seismic waves. Maximum shear modulus (Gmax) and shear wave velocity (Vs) are two essential parameters employed to perform dynamic analysis.

Frequencies 5-12 Hz resolve Vs3 the shear 2019-05-28 is the shear modulus (in Pa), V s is the shear wave velocity (in m/s), and ρ is the density (in kg/m3). s G max and V s are primarily functions of soil density, void ratio, and effective stress, with secondary influences including soil type, age, depositional environment, cementation and stress history Hardin and Drnevich (1972).

As some of these indexes are variates belonging to interval shear wave velocity can be modified according to the frequency. The concepts of apparent masses and dynamic coupling between water and solid were introduced by Biot to explain the slight variation of the shear wave velocity as the wave frequency increases. 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/sec2 or 32.2 ft/sec2).

From Eq. (1), shear wave velocity governs shear modulus. Sheeran, et al., (1967) studied the shear wave velocity of com-compacted clayey soils to compaction water content. At constant water content, the shear wave velocity increased with dry density Shear wave propagation in soil is a physical phenomenon and has been used widely for monitoring and seismic property assessment in geotechnical engineering. Shear wave velocity V s and small-strain shear modulus G 0 are the key parameters in defining material response to various dynamic loadings. This study investigates the correlation between shear wave velocity (\(V_{\mathrm{S}}\)) and standard penetration test blow counts (SPT-N value) in all soil types, gravelly soil, sandy soil and clayey soil for Mashhad city in the north eastern region of Iran. parameter has been discovered to have a direct correlation with the small-strain shear wave velocity of a soil [1].
