Shear wave velocity (vs), dynamic shear modulus G,,,, and damping characteristics of soils are important parameters required for dynamic site response analysis as well as for design and performance evaluation of earth structures and foundations. Proper choice of such input soil parameters is an

Abstract: A database of shear-wavevelocity (V s) measurements using a variety of techniques and soil properties measured on high-quality samples for 28 Norwegian sites has been established. The purpose was to evaluate the different methods of measuring V s, to present guide- …

parameter has been discovered to have a direct correlation with the small-strain shear wave velocity of a soil [1]. In other words, shear wave velocity in low strains can be used as a unique and reliable parameter that can be used in microzonation maps.

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). G max the shear wave velocity of sand. The shear wave velocity is a dynamic param-eter highly dependent upon variables such as void ratio, conﬁning pressure and strain amplitude in the material. Research has shown that the shear wave velocity can be estimated through empirical CPT-relations. 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 velocity (Vs). studies have shown that conﬁning stress, soil type/plasticity, and void ratio/relative den-sity are the most important factors inﬂuencing the variation of shear modulus, or shear wave velocity, with shear strain amplitude (e.g., Hardin and Drnevich 1972, Kramer 1996, Ishihara 1996).

Both shear and Young moduli were compared with the shear wave velocity of soil, with R 2 and RMSE of 0.96–0.97 and 0.48–3.5 MPa respectively. The major advantage of this technique is that input and output signal data can be stored in a computer that can be used to calculate soil …

Maximum shear modulus is the equivalent term for the shear modulus of a soil when undergoes strain levels equal or less than 10-3. Having been determined, G max The shear-wave velocity (V S) is one of the most important parameters for determining dynamic soil properties and ground-response analyses. The seismic surface wave method (MASW) is the simplest and a very efficient way of measuring the shear-wave velocity in the field.

Soil type A is rock crystalline, and similar soil types with wave shear velocity more than 914 m/s (3000 ft./s). Soil type B is dense soil from strong alluvium or dense sands, silts, and stiff clays with shear strengths more than 72 kPa (1500 psf), and is for depths less than 60 m (200 ft.) and overlying rock strata.

d s u m m is possible to include water composition in soil water and surface water. even though the locations of maximum erosion (primarily by waves in exposed shallow waters) and flow velocities and short transport times to the surface. 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). G max has units of force per length squared (i.e., kPa or psf). Soil type A is rock crystalline, and similar soil types with wave shear velocity more than 914 m/s (3000 ft./s).
