摘　　要：对用于建设某大型石油储罐的抛石填海夹杂淤泥质土的地基分区选择不同高能级强夯工程进行试夯试验.采用浅层平板载荷试验、超重型动力触探试验、瑞利波试验对处理的地基进行效果检测,结果表明抛石填海地基经高能级强夯处理后承载力、压缩模量等明显提高,沉降明显减小,地基各项力学性能指标均能满足设计要求,证明试夯采用的强夯设计参数正确、施工工艺合理.To build a large oil storage tank on high energy dynamic compaction, this paper makes a tamping test on the treatment of riprap reclamation with silt soil foundation by using the plate loading test, ultra heavy dynamic sounding, and Rayleigh wave. The results show that the bearing capacity,settlement, compression modulus of the riprap reclamation foun-dation improves significantly, and settlement decreases significantly, and the mechanical properties can meet the design requirements on high energy level dynamic compaction. It ’s proved that the design parameters of high energy dynamic compaction are correct, and the construction technology is reasonable.
