Based on the pile driving logs,geological conditions on site and results of high-strain dynamic pile-driving tests of the steel tubular piles driven in decomposed rocks,the effect of diesel and hydraulic hammers in driving these piles is analyzed.The results of the analysis show that a hydraulic hammer produces a higher transfer coefficient of driving energy and the effective transfer coefficient of the hydraulic hammer used on the present project is 2.58 times that of a diesel hammer.
