The average values of the shear wave velocity (Vs) of each soil layer are obtained, as listed on Table 1. The soils at depths from to m consisted of interbedded layers of sandy silt and fine sand. Due to the various soil types, it is difficult to interpret the S-wave data in these soil Size: KB. Maximum shear modulus (Gmax) and shear wave velocity (Vs) are two essential parameters employed to perform dynamic analysis. Shear modulus of the soil highly depends on strain levels. Maximum shear modulus is the equivalent term for the shear modulus of a soil when undergoes strain levels equal or less than Having been determined, G. Relationship between Shear-Wave Velocity and Geotechnical Parameters for Norwegian Clays Jean-Sebastien L’Heureux, Ph.D.1; and Michael Long2 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. PDF | The theoretical analysis shows that it is possible to obtain water content, by measuring the shear waves velocity. The comparisons | Find, read and cite all the research you need on.

potential, soil seismic response, assessment of the effectiveness of soil improvement methods used in soils, identification and transportation of pollutants in soils, as well as others [1]. The measurement of shear waves velocity V. s. is accomplished either by geophysical tests in the field, or laboratory tests. Among the laboratory tests, two.   Shear wave velocity (V S) can be obtained using seismic tests, and is viewed as a fundamental geotechnical characteristic for seismic design and seismic performance evaluation in the field of earthquake engineering. To apply conventional geotechnical site investigation techniques to geotechnical earthquake engineering, standard penetration tests (SPT) and Cited by: How to Measure Shear-Wave Velocity (Vs) Vs can be measured through several different approaches: surface-wave survey, refraction survey, down-hole survey, cross-hole survey, and laboratory measurement (see illustrations below). The first two are non-destructive in-situ methods, while the others require preparation of borehole(s) and some. The shear wave velocity of the soil can also be used to determine the soil profile type. The shear wave velocity can be measured in-situ by using several different geophysical techniques, such as the uphole, down-hole, or cross-hole methods. Other methods that can be used to determine the in-situ shear wave velocity include the seismic cone File Size: KB.

Christchurch, New Zealand Unified Correlation between SPT-N and Shear Wave Velocity for all Soil Types C.-C. Tsai1 and T. Kishida2. ABSTRACT. The shear wave velocity (Vs) of sediments plays a key role in seismic wave and is amplification required in site response analysis. uch information isS usually lacking during field exploration, but. shear wave velocity measurement (13 ft) and 11 m (36 ft) where the shear wave velocities increase corresponding to a noticable increase in the cone bearing. soil parameters, namely, the insitu measured shear wave velocity, and the unit weight. The unit weight may be also determined with sufficient accuracy, by means of another empirical expression, using the P-wave velocity. It is indicated that once the shear and P-wave velocities are measured insitu by an appropriate geophysical survey, the allowableFile Size: KB. Crosshole geophysical testing determines the shear wave velocity of soils which provides an indication of it’s stiffness. Until recently this method has not been commonly used for liquefaction assessment and is relatively specialised. How is it useful and is it required on my site? Using shear wave velocity measurements from this test, the.
