Characterization on the correlation between shear wave velocity and piezocone tip resistance of Jiangsu clays

Correlations between shear wave velocity and cone tip resistance in natural clays

For design of foundation, engineering properties like strength and deformability characteristics of soils are very important parameters. Soil properties like cohesion, angle of friction, shear wave velocity, Poisson’s ratio etc. are important for evaluation of the vibration parameter by numerical modeling of soil. In various numerical modeling software manuals, various ranges of these parameters are specified. If any of these software is used, the output results of a problem are mostly very sensitive to these input parameters. Hence, selection/estimation of proper values of these engineering properties of soil is very critical for analysis of a geotechnical engineering problem. Twelve empirical correlations of soil properties in terms of common field Standard Penetration Test (SPT)-N value have been developed through random number generation technique. The usefulness of the presently developed correlations is verified by validating the correlations with experimental values available in literature, which in turn can be used for geotechnical engineering design problems.

Estimation of Engineering Properties of Soils from Field SPT Using Random Number Generation

Estimating shear wave velocity of soil deposits using polynomial neural networks: Application to liquefaction

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 piezocone penetration tests (CPTu) were undertaken together with a variety of borehole seismic tests for a range of sites in Korea. Statistical modeling of the in-situ testing data identified correlations between V
 S and geotechnical in-situ penetration data, such as blow counts (N value) from SPT and CPTu data including tip resistance (q
 t), sleeve friction (f
 s), and pore pressure ratio (B
 q). Despite the difference in strain levels between conventional geotechnical penetration tests and borehole seismic tests, it is shown that the suggested correlations in this study is applicable to the preliminary determination of V
 S for soil deposits.
