Mechanism of Dynamic Consolidation and Its Environmental Effect

This paper is contributed as case histories in ground soil improvement with particular emphasis of dynamic consolidation. The authors try to present as much as they got from the field testings and observations including vibrational parameters, pore pressures, stereoscopic photogrammetry, etc. in order to trace the real behaviour of ground movement during tamping. It is believed that all the data got from the field work are rather informative and illustrative than that from theoretical modelling in the laboratory. Thus, some highlights relating effective thickness of compaction, maximum spacing between compaction points, number of blows for optimum tamping and seismic attenuation for environmental consideration are given
