- Abstract
- Field energy measurements on Japanese drill rigs were made during the performance of the Standard Penetration Test to document the difference between Japanese and present U.S. Practice. A total of 78 Standard Penetration Tests were performed using 19 different testing conditions (equipment and operators). Over 2000 data points are reported.
