USE THE SPT TO MEASURE DYNAMIC SOIL PROPERTIES?--YES, BUT....!

This article reviews the statics and dynamics of the standard penetration test, with emphasis on stress wave analyses. The author agrees a properly standardized SPT has a reasonable, already partly demonstrated potential for quantitative correlations with a factor of safety against liquefaction, with the J damping coefficients in pile- driving problems, and perhaps with high- and low-strain shear wave velocity. However, he recommends establishing and enforcing an alternative ASTM Method D1586 standard that requires a mechanized hammer drop, a calibrated energy content in the first compression wave in the rods, and the use of rotary drilling in a hole kept full with drilling mud.
