Abstract：A series of energy levels of dynamic compaction（DC）（3000 kN.m,6000 kN.m,8000 kN.m and 10000 kN.m） were successfully used in practice on a rubble fills site in coastal area for the first time in China.The experiment provided the parameters for the design,construction and detection of 10000 kN.m DC.The monitoring results of standard penetration test（SPT） were analyzed and compared with those of other energy levels.Some conclusions such as effective depth of improvement（EDI） on rubble fills site with 10000 kN.m DC were acquired.It was suggested that the EDI should take 1316 m for gravel and sand,which might be uesd in the Table 6.2.1 of Ground Treatment Code of China.
