For the dynamic compaction construction, the contact surface of the dynamic compaction foundation rammer is not necessarily the larger the contact surface of the rammer, but the more the dynamic compaction construction conforms to the actual situation of the foundation, the better, which mainly depends on the static pressure of the rammer.

静压力是指当这个静压力小于标准范围时夯击地面会导致外表坚固、低沉松软，那静压力是越大越好吗，不尽然，当静压力大约某个点也可导致夯锤夯力过大堕入地基无法拔出形成施工困难。

Static pressure means that when the static pressure is less than the standard range, ramming the ground will lead to a solid, low and soft surface. Is the greater the static pressure, the better? Not necessarily. When the static pressure is about a certain point, it can also lead to excessive ramming force of the rammer falling into the foundation and unable to pull out, resulting in construction difficulties.

在分层动态压实施工的实施中，一层强夯的高度从8-12米的填充高度开始，小于此高度的一层填充不使用动态压实，并且上部路堤填充8Mi会进行动态压实，直到到达路堤顶部为止。

In the implementation of layered dynamic compaction construction, the height of one layer of dynamic compaction starts from the filling height of 8-12m, the filling of one layer less than this height does not use dynamic compaction, and the upper embankment filling of 8mi will be dynamically compacted until it reaches the top of the embankment.

强夯机的夯锤应为具有较高弹性模量的圆柱形钢夯，或为将钢筋混凝土浇注在厚钢外壳中的圆柱形夯，夯锤的重量为10 吨，在其夯锤的底部，应对称设置与顶部表面相连的4-6个通风孔，以便夯锤可以在提起锤子时清洁底部的空气并减少坑底部的吸力。

The rammer of the dynamic rammer shall be a cylindrical steel rammer with high elastic modulus, or a cylindrical rammer that casts reinforced concrete in a thick steel shell. The weight of the rammer is 10 tons. At the bottom of the rammer, 4-6 ventilation holes connected to the top surface shall be symmetrically set, so that the rammer can clean the air at the bottom and reduce the suction at the bottom of the pit when lifting the hammer.

强夯可以通过相应的方法进行处理。初步调查应特别关注检查地下管道和结构的特定位置，以防止对其造成损坏。在到达施工现场之前，强夯设备应使用推土机将道路施工现场弄平。这样可以方便动力压实机的进入，使强夯施工更加方便。

Dynamic compaction can be treated by corresponding methods. The preliminary investigation shall pay special attention to the inspection of specific locations of underground pipelines and structures to prevent damage to them. Before arriving at the construction site, the dynamic compaction equipment shall use bulldozers to level the road construction site. This can facilitate the access of the power compactor and make the dynamic compaction construction more convenient.
