【Abstract】 A mode was proposed to describe the lateral improvement degree for single point pounding for dynamic compaction on cohesiveless soils. Based on the proposed mode, an approach was put forward to calculate the improvement between pounding points for multi\|points for multi\|point pounding. The locations with least improvement were found to be in the middle between pounding points and in the center of four pounding points, where the relationship between the improvement and the dimensionless spacing has been established by making use of the results of the model tests carried out by K.S.Heh and A.Oshima.更多还原
