The dynamic compaction project of the Xiangyin Golden Dragon Science and Technology Port Project is located in the Golden Dragon Town, Xiangyin County, Hunan Province. The soil backfill dynamic compaction covers approximately 100,000 square meters. The overall foundation treatment construction area plans to use two passes of 4000KN.m point compaction, which should meet a post-tamping settlement of no more than 100mm, with a 5m x 5m plum blossom pattern, and one pass of 2000KN.m full compaction, with hammer impressions overlapping by 0.8d (the construction area is approximately 100,000 square meters). The specific amount of work will be determined by the final construction area. The compressive modulus within the treatment depth range should be Es≥8MPa, and the characteristic value of the foundation bearing capacity should be not less than 160KPa.
