地基基础的应力充分扩散，应该把强夯地基处理的范围增大，至少需大于基础范围，构筑物的类型以及重要性决定着具体放大范围。
When the stress of foundation is fully spread, the scope of dynamic compaction foundation treatment should be enlarged, at least larger than the scope of foundation. The type and importance of structures determine the specific enlargement scope.
有相关规定，一般的建构物每个方位边界超过地基基础外缘的宽度，最好是设计处理的三分之一到二分之一，需大于三米的距离。如果建构物很重要，强夯影响深度的处理范围要向外围扩大。
It is stipulated that the width of each azimuth boundary of a general structure exceeds the width of the outer edge of the foundation, preferably one third to one half of the design treatment, and the distance should be greater than three meters. If the structure is important, the treatment scope of the impact depth of dynamic compaction should be extended to the periphery.
