强夯法加固地基的机理，首先应该分为宏观机理和微观机理。其次，对饱和土和非饱和土应该家以区分，而在饱和土中，粘性土与无粘性土还应该加以区别。另外对特殊土，如湿陷性黄土等，应该考虑它的特征。再次，在研究强夯法机理时应该首先确定夯击总能量中真正用于加固地基的那一部分，而后再分析此部分能量对地基土的加固作用。
The mechanism of dynamic consolidation for foundation reinforcement should be divided into macro mechanism and micro mechanism. Secondly, saturated soils and unsaturated soils should be distinguished, and cohesive soils and non-cohesive soils should be distinguished in saturated soils. In addition, the characteristics of special soils, such as collapsible loess, should be considered. Thirdly, when studying the mechanism of dynamic compaction, we should first determine the part of the total energy of dynamic compaction that is really used to reinforce the foundation, and then analyze the reinforcement effect of this part of energy on the foundation soil.
地基土经强夯法加固后，其强度提高过程大致可分为四个阶段：夯击能量转化，同时伴随强制压缩或振密(表现为土体中水及气体排出，孔隙水压力上升化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机);土体液化或土体结构破坏(表现为土体强度降低或抗剪强度丧失);排水固结压密(表现为渗透性能改变，土体裂隙发展，土体强度提高);触变恢复并伴随固结压密(包括部分自由水又变成薄膜水，土的强度继续提高)。
After the foundation soil is strengthened by dynamic compaction, the process of strength improvement can be roughly divided into four stages: energy conversion of compaction, accompanied by forced compression or vibration compaction (manifested as water and gas drainage, pore water pressure rise); liquefaction of soil or structural damage of soil (manifested as soil strength reduction or shear strength loss); drainage consolidation compaction (manifested as permeability change, soil cracks development). Thixotropic recovery is accompanied by consolidation and compaction (including partial free water turning into film water, and soil strength continues to increase).
