不同的工程中，根据设计要求与基础形式的不同，强夯地基处理的目的可能不尽相同。当强夯处理后的场地直接作为基础持力层时，强夯法作为地基的最终处理手段，以提高地基承载、减小地基沉降量与不均匀沉降为目的。
In different projects, the purpose of dynamic compaction foundation treatment may vary depending on design requirements and foundation forms. When the site after dynamic compaction treatment is directly used as the foundation bearing layer, the dynamic compaction method is used as the final treatment method for the foundation, with the aim of improving the foundation bearing capacity, reducing the foundation settlement and uneven settlement.


当采用强夯进行地基处理后采用桩基础的，强夯法作为地基预处理手段，以消除土体欠固结性、提高土体强度指标为目的。
When using dynamic compaction for foundation treatment followed by pile foundation, the dynamic compaction method is used as a foundation pretreatment method to eliminate soil underconsolidation and improve soil strength indicators.


当地质条件与土体性质不同时，强夯地基处理的目的也可能不同。湿陷性黄土场地，强夯处理的目的以消除湿陷性为主；粉砂、细砂场地，强夯处理的目的以消除液化为主；沿海吹填场地，强夯处理的目的以提高土体密实度、加速土体固结为目的；高填方场地，强夯处理的目的以提高土体密实度、提高地基承载力、减小地基沉降量与不均匀沉降、提高场地稳定性为目的。
When the geological conditions and soil properties are different, the purpose of dynamic compaction foundation treatment may also be different. The purpose of dynamic compaction treatment for collapsible loess sites is mainly to eliminate collapsibility; The purpose of dynamic compaction treatment for sites with fine sand and silt is mainly to eliminate liquefaction; The purpose of dynamic compaction treatment for coastal reclamation sites is to improve soil compaction and accelerate soil consolidation; The purpose of dynamic compaction treatment for high fill sites is to improve soil compaction, increase foundation bearing capacity, reduce foundation settlement and uneven settlement, and enhance site stability.
