Abstract
Taking railway branch line in Qinzhou Bonded Port, Guangxi as the on-site experimental study on dynamic compaction processing and consolidation subgrade is carried out. The result shows that due to multiple actions of free engineering background, the effect of hydraulic fill sand settling, sand body squeezing,and vertical dynamic stress by strong tamping, most of the sludge in sea silt layer is forced out, the pore water and gas inside the sand body is exhausted, soil particles move together, and then soil mass is compacted so that the consolidation effect is good and the bearing capacity is increased significantly by 180 kPa more than the design requirement.关键词
