Field measurement of shear wave velocity of soils Fanyu Zhu, K.R. Peaker and Shaheen Ahmad Shaheen and Peaker Limited, Toronto, Ontario, Canada ABSTRACT In this study, S-wave velocity survey was carried out at a site near a drilled borehole. The test data of a firm silty clay. The objectives of this study are to investigate the relationship between static and dynamic elastic moduli determined using shear-wave velocity measurements and to demonstrate the practical potential of the shear-wave velocity method for in situ dynamic modulus evaluation. Three hundred by mm concrete cylinders were prepared from three different mixtures with target compressive Cited by: 5.
Jun 01, · This paper deals with determination of shear wave velocity in the soil directly in-situ by dynamic tests. Self-developed dynamic excitation impulse device was used in order to excite the soil during the tests. Consequently, accelerations of the soil vibration were measured by portable five-channel measurement equipment. Recorded data were evaluated by self-developed Square of Accelerations Author: Milan Sokol, Lenka Konecna. The dynamic properties of the soil can be determined in two different ways. The first one is the common way, using the Rayleigh Waves dispersion on the soil surface, and the back calculation to shear wave profiles. The second approach is the back calculation of the .
investigated the effect of compaction energy on the shear stiffness of compacted soil. This paper examines the effect of compaction en-ergy on the dynamic properties of compacted soil, namely the shear wave velocity and the small strain shear modulus. Specimens compacted at moisture contents ranging from dry to wet of OMC under. The small-strain shear modulus depends on stress in uncemented soils. In effect, the shear-wave velocity, which is often used to calculate shear stiffness, follows a power equation with the mean effective stress in the polarization plane V s = α (σ m ′ / 1 kPa) β, where the α factor is the velocity at 1 kPa, and the β exponent captures the velocity sensitivity to the state of stress.

Small-strain shear wave velocity measurements provide a promising supplement and in some cases, where only geophysical measurements are possible, may be the only alternative to the penetration-based approach.
This report presents guidelines for evaluating. Seismic CPT to Measure In-Situ Shear Wave Velocity. A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination of the seismic downhole method and the CPT logging provide an extremely rapid, reliable and economic means of determining stratigraphic, strength and modulus Cited by: Dec 15, · Ohta T, Goto N, Kagami H, Shiono K () Shear wave velocity measurement during a standard penetration test.

A shear wave is generated at one boundary of a soil specimen and then received at an opposite boundary. The shear wave travel time is measured, which over a known travel distance yields the shear wave velocity. 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).

Shear wave velocity is an important parameter for evaluating the dynamic behaviour of soil in the shallow subsurface. Thus site characterization in calculating seismic hazards is usually based on the near surface shear wave velocity values. The average shear wave velocity for the top 30 m of soil is referred to as V S For earthquake Cited by: Nov 11, · 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. Significant prior publications dedicated to dynamic soil properties are cited. Two major advancements in dynamic soil property measurement are highlighted, namely: Combined cyclic torsional shear and resonant column, and wave propagation velocity measurements with bender gemhallphotography.com by: This paper was attempted to determine dynamic characteristics of peat soil such as shear wave velocity (Vs) using Multi-channel Analysis of Surface Wave (MASW) technique and shear modulus using a conversion of shear wave velocity with empirical formula where the density of peat was needed thus the density were calculated after collecting the Cited by: 2.
Among these testing methods, the shear wave velocity technique is thought to best represent the dynamic properties of soils. Because the soil liquefaction phenomenon is directly related to the dynamic properties of soil, the shear wave velocity /96/$ Elsevier Science gemhallphotography.com by: 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.
