Dynamic compaction and dynamic compaction replacement are two common foundation treatment methods in construction engineering, but there are some differences between them. There are many kinds of dynamic compaction methods, dynamic compaction and dynamic compaction replacement are two completely different concepts. In the process of dynamic compaction construction, the dynamic compaction method means to drop the heavy hammer at a certain height and produce the purpose of compaction, so as to achieve the effect of improving the bearing capacity of the ground.

强夯置换的方法则是要关于地上进行必定的填充物的参加，这样去一点一点的把地基土体给换掉，这样可以到达关于土质的改进，一般的强夯法是无法到达这样置换的意图和作用的。

The method of dynamic compaction replacement is to take part in certain filling materials on the ground. In this way, the foundation soil can be replaced bit by bit. In this way, the improvement of soil quality can be achieved. The general dynamic compaction method can not achieve the intention and effect of such replacement.

在强夯置换中是可以很明显的去改进，进步脆弱地基的承载才能。用锤体进行必定高度下的夯击，让土层敏捷的得到加固。在进行施工的时分，强夯置换主要是可以进行加固饱以及对土地进行改进的方法，而强夯置换的时分和强夯法固然是不同的，所运用的锤体落差发生的高冲击也会关于碎石、土体进行强行的揉捏方法。

In dynamic compaction replacement, it can be obviously improved to improve the bearing capacity of fragile foundation. The hammer body is used to tamp at a certain height, so that the soil layer can be quickly reinforced. During the construction, dynamic compaction replacement is mainly a method to reinforce and improve the soil, while the time division of dynamic compaction replacement is different from that of dynamic compaction method, and the high impact caused by the drop of hammer body will also be forced to knead the gravel and soil.

这样在地基的处理中就形成了一种置换的方法，一起可以提高地基的承载才能，削减地基所带来的拱起，关于强夯置换的运用，是有土质的要求的，一般在高饱和和粘性土中是常用的，全体的作用仍是要去看夯实的作用以及强夯法的运用，这样才可以确定在运用的过程中关于地基的改进和替换，还可以到达地基夯实的意图，关于修建和运用都是有肯定的优势和优点的。

In this way, a replacement method is formed in the foundation treatment, which can improve the bearing capacity of the foundation and reduce the arching caused by the foundation. The application of dynamic compaction replacement has the requirements of soil quality, which is commonly used in high saturated and cohesive soil. The whole function still depends on the role of compaction and the application of dynamic compaction method, so as to determine the direction of application In the process of foundation improvement and replacement, we can also reach the intention of foundation compaction. There are certain advantages and advantages in construction and application.
