摘　　要：强夯法处理深厚填土具有良好的经济和社会效益,但由于土体参数的复杂性,强夯设计还没有十分严密的理论分析方法,无法精密地计算和定量预测,各种检测技术结果的相关关系还不十分明确。本文通过某大面积深厚回填土地基处理的工程实例,阐述了强夯地基处理的设计、施工及检测的全过程,并通过对动力触探测试、瑞雷波测试及浅层平板载荷试验等检测结果的比较,初步分析了在不同夯击能下各检测方法的相关关系,总结了在含粗颗粒回填土中各种检测方法的适用性,可为类似工程强夯工作提供参考。Dynamic compaction method has good economic and social benefits to treat thick filling soil. Because of the complexity of the soil parameter determination, there is no strict theoretical analysis to calculate and predict quantitively in dynamic compaction design. The correlation between various effect inspection methods is not very clear. A dynamic compaction design scheme for a ground treatment project of large deep filling ground is presented to demonstrate the design, construction and inspection process. The correlation of various inspection methods under the different compaction energy is discussed, and the applicability of various inspection methods in coarse granular filling is summarized based on the comparison of the dynamic penetration test, Rayleigh wave test and plate loading test etc. It could be referred for the similar projects.
