摘　　要：利用强夯试验的现场数据,建立了单点夯沉量与夯击次数的关系模型,揭示了单击夯沉量随夯击次数的变化规律;基于岩土体变形的结构耗散理论,从能量的角度分析了夯击能对系统的有效进化作用随夯击数的变化规律,并以此解释了夯沉量-夯击数的关系曲线规律,进一步阐明了强夯加固地基的内在机制。According to the origin data of dynamic compaction test,relation model of settlement and ramming number is established,the pattern of settlement changing with ramming numbers is outlined.Based on dissipative structure theory of geotechnical materials deformation,discussions are carried out on the law of the effective evolving function denoted by tamping energy changing with increasing ramming numbers,and explain the settlement-ramming numbers relational curve rule by this,further elucidate the inherent mechanism of dynamic compaction.

关 键 词：夯击数 夯沉量 夯击能 耗散理论
