Various investigators have developed relation-ships between shear wave velocity and liquefaction resistance. the shear modulus, G, soil density, p, and shear wave velocity, V, as follows, G=o V", (1) Hence, the shear modulus can be determined using in-situ seismic methods for the determination of the shear wave velocity. The shear modulus is largest at low strains and decreases with increasing shear strain (9).

The velocity can then be determined and compared against the initial estimate. Freeboard compensates for effects such as wave action, localised The shear at the interfaces between the areas should be taken as zero.

It is useful as a method in fluid mechanics to compare true velocities, such as the velocity of a flow in a stream, to a velocity that relates shear between layers of flow.

Shear wave velocity (V s) induced shear modulus known as a key geotechnical property corresponded to small strain which is important in earthquake investigations. Because of limitations in obtaining undisturbed sample especially in granular soils, in situ seismic tests instead of laboratory measurements are directly ideal tests to achieve the V s . 2020-08-15 25 rows 2019-05-23 Shear wave velocity is directly related to earthquake energy characteristics and is a useful parameter in estimating the surface motion parameters.
