Abstract
In this study, the pilot tests on the reclaimed land were performed in order to fing the suitable construction method with dynamic compaction TypeⅠ, TypeⅡat different dynamic energy and hydraulic hammer compaction. The estimation of the compaction through the various pilot tests was performed by the CPT-qc, SPT-N and field density tests.
As the result of the pilot tests, is shows that the dynamic compaction method is better than the hydraulic hammer compaction method in the effect of the ground improvement, espectially dynamic compaction TypeⅠis much superior to others. When it comes to method for measuring the intensity of the ground, the value of the cone penetration test-resistance(qc)is much suitable for the ground. Besides, the standards for the compaction control, which showed that over 10Mpa at 0 through 5meters in the upper layer and 7Mpa at 5 through 8meters in the lower layer in the CPT-qc, could be found without discrimination of the upper road and lower road on the reclaimed land. And it also found that the intensity of the reclaimed land gets back to the original status in about throung 15days.
