Spt standard penetration test and soil liquefaction

Abstract Evaluation of the liquefaction potential of a liquefaction-prone area is important for geotechnical earthquake engineering, both for assessment for site selection and for planning and new constructions. The liquefaction potential index for the city of Duzce in northwestern Turkey using the empirical relationships between the Standard Penetration Test SPT and the Shear Wave Velocity Test was investigated in this study. After, values based on SPT blow counts were obtained from the alluvial soils in the city of Duzce. The liquefaction potential indexes of the soils were determined using the empirical relationships between the Standard Penetration Test SPT and the Shear Wave Velocity Test calculating for a probable earthquake of.

Standard penetration test - Wikipedia

Procedure[ edit ] The test uses a thick-walled sample tube, with an outside diameter of This is driven into the ground at the bottom of a borehole by blows from a slide hammer with a mass of The sum of the number of blows required for the second and third 6 in. The blow count provides an indication of the density of the ground, and it is used in many empirical geotechnical engineering formulae. Purpose[ edit ] The main purpose of the test is to provide an indication of the relative density of granular deposits, such as sands and gravels from which it is virtually impossible to obtain undisturbed samples. The great merit of the test, and the main reason for its widespread use is that it is simple and inexpensive.
