| In spite of many advantages such as the simplicity in test procedure, Standard Penetration Test(SPT) results contain some errors caused by the variability of test equipment, instruments and test procedures. Especially, it is inevitable that the measured SPT hammer energy is different from the theoretical value because of energy loss. In this paper, the hammer energy level is measured during the performance of the field SPT in Korea by using a ultra-sonic system and PC.program. As the results of this study, the average hammer energy ratio of the R-P hammer and the Trip hammer is calculated at 64.2%, and at 75.0% respectively. The average energy ratio of the SPT for the R-P hammer is calculated at 46% and at 54% for the Trip hammer, by applying the rod energy ratio 0.72. |
