强夯施工中由于基础的应力扩散作用和抗震设防要求，强夯处理范围应大于建筑物基础范围，具体范围可根据建筑结构类型和重要性等因素确定。
Due to the stress diffusion effect of the foundation and seismic fortification requirements in dynamic compaction construction, the scope of dynamic compaction treatment should be larger than that of the building foundation. The specific scope can be determined based on factors such as the type and importance of the building structure.


对于一般建筑物，每边超出基础外缘的宽度宜为基底下设计处理深度的1/2～2/3，并不应小于3m。对可液化地基，每边应超出基底下设计处理深度的1/2，并不应小于5m。对湿陷性黄土地基，应满足下列要求：
For general buildings, the width of each side beyond the outer edge of the foundation should be 1/2 to 2/3 of the design treatment depth below the foundation, and should not be less than 3m. For liquefiable foundations, each side should exceed 1/2 of the design treatment depth below the foundation, and should not be less than 5m. For collapsible loess foundations, the following requirements should be met:


(1)当为局部处理时，非自重湿陷性黄土场地，每边应超出基础底面宽度的1/4，并不应小于0.5m；自重湿陷性黄土场地，每边应超出基础底面宽度的3/4，并不应小于1m；
(1) When dealing with local areas, for non self weight collapsible loess sites, each side should exceed 1/4 of the width of the foundation bottom and should not be less than 0.5m; for self weight collapsible loess sites, each side should exceed 3/4 of the width of the foundation bottom and should not be less than 1m;


(2)当为整片处理时，超出建筑物外墙基础外缘的宽度，每边不宜小于处理土层厚度的1/2，并不应小于2m。
(2) When processing the entire area, the width beyond the outer edge of the building's exterior wall foundation should not be less than 1/2 of the thickness of the treated soil layer on each side, and should not be less than 2 meters.
