摘　　要：通过一代表性强夯处理填土地基事例 ,在大量的测试资料及其他有关强夯文献资料广泛分析的基础上 ,作出了强夯加固模式图 ;并根据强夯地基土密实度改变的特点、夯沉量与强夯加固深度的关系 ,建立了填土地基强夯有效加固深度及加固宽度的计算公式 该公式同样对其他较均质的非饱和土体适用 ,对估算地基加固范围 ,尤其是在试夯时估算地基加固范围 。Through the analysis of a large number of materials related to dynamic compaction and a representative tamped ground engineering,the pattern of the ground improvement by heavy tamping has been put forward,and a formula for calculating the width and depth improved by dynamic compaction is derived,in which the character of the soil density changed by tamping and the relationship between the depth and settlement of tamping are considered. This formula is very useful to estimate the depth and width of tamped ground.
