maximum shear modulus of soil is function of the shear wave velocity, V s, and soil density G max = tV s 2. The V s can be determined directly by testing undisturbed soil samples in laboratory or computed using in-situ meas-urements [Brandenberg et al. 2010]. The V s is also used for the seismic soil classiﬁcation in building codes.

Shear wave velocity of soil

1 INTRODUCTION. The small-strain shear modulus of soils,. Gmax, is an Abstract. Shear wave velocity values obtained from in situ mea- surements are used to compute the low strain soil shear modulus required as an input parameter Dynamic soil stiffness, as indicated by either shear modulus or shear wave velocity, Average Shear Wave Velocities in Soils of the Los Angeles,. California In addition, soil samples collected at both sites were tested using the resonant column method to evaluate dynamic properties. The shear wave velocities The large earthquakes continue producing heavy damages, part of which are associated with failures induced by soil liquefaction. Accordingly, efforts to improve Dec 7, 2016 Usually, a water-saturated unconsolidated deposit has a seismic velocity of about 1500 to 1600 m/s.

The shear modulus is related to shear wave velocity as 2 max = ρG V s [3] where Gmax is small-strain shear modulus in Pa, ρ is the soil density in kg/m3, and V s is the shear wave velocity in m/s. The compression wave (P-wave) velocity, Vp, can be derived from the S-wave velocity (Vs) and the Poisson’s ratio (ν) as ν ν 1 2 2(1 ) − − =V V p s [4]

In this paper, the shear wave velocity and small strain shear modulus of soft to firm clays are evaluated from results of consolidation tests. The site-specific constants that relate the void ratio to the in-situ shear wave velocity is attained from the undisturbed virgin compression curve acquired from a consolidation test. The in-situ

Among them, the shear wave velocity cor-rected for overburden stress (V s1) is considered to offer Supporting: 2, Contrasting: 1, Mentioning: 66 - Abstract An investigation to systematize empirical equations for the shear wave velocity of soils was made in terms of four characteristic indexes. The adopted indexes are the N‐value of the Standard Penetration Test, depth where the soil is situated, geological epoch and soil type.

Meanwhile, at Sejagung Sri Medan indicated the shear wave velocities for loose soil was between 220 m/s and 450 m/s, very dense In this paper, the shear wave velocity and small strain shear modulus of soft to firm clays are evaluated from results of consolidation tests. The site-specific constants that relate the void ratio to the in-situ shear wave velocity is attained from the undisturbed virgin compression curve acquired from a consolidation test. The in-situ 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. The shear wave velocity (vs) is theoreti-cally related to the shear modulus and thereforeis a direct measurement of the small strain shear modulus (Gmax).

The in-situ 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.

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.
