Definition and difference of full compaction and point compaction in dynamic compaction construction

强夯地基处理以施工工艺区分，可列为三类：满夯、主夯、复夯。其间主夯和复夯的区分一般是依据夯锤的力量级别来界说的。

Dynamic compaction foundation treatment is distinguished by construction technology and can be divided into three categories: full compaction, main compaction and re compaction. The distinction between main ramming and re ramming is generally defined according to the power level of rammer.

主夯一般也是说的点夯，其重锤夯实力量归于高力量级其他，要点运用于深的地方的处理；复夯的力量级是主夯力量级的二分之一，也可依据夯坑的深来确认能级。用到复夯的一般得具有相应的条件：在点夯完结施工后，夯坑的很深，即可选用复夯。

The main rammer is also generally referred to as point rammer. The ramming force of its heavy hammer belongs to the high force level, and other key points are applied to the treatment of deep places; The power level of re tamping is half of that of main tamping, and the energy level can also be confirmed according to the depth of tamping pit. Generally, the re tamping shall have corresponding conditions: after the point tamping is completed and the tamping pit is very deep, the re tamping can be selected.

满夯是对整个场所进行夯实处理，然后加大土质的密实度，从而进步场所的地基承载力。满夯和点夯工作方法不同，可是都归于强夯施工的方法。

Full compaction is to tamp the whole site, and then increase the compactness of the soil, so as to improve the foundation bearing capacity of the site. The working methods of full compaction and point compaction are different, but they all belong to the method of dynamic compaction.

满夯和点夯的区别如下：

The difference between full compaction and point compaction is as follows:

点夯在3米以内，根底加固深较浅。并且是独立的根底，那么只用采纳点夯就行。满夯在3米以上，根底加固深较深。并且是接连的根底，这种状况应先选点夯方式，完结后再进行满夯施工处理。一起依据加固的深来挑选夯锤分量与夯击力量。

The point ramming is within 3M, and the reinforcement depth of the foundation is shallow. And it is an independent foundation, so just adopt a little tamping. The full compaction is more than 3m, and the foundation reinforcement is deep. And it is the basis of continuous compaction. In this situation, the point compaction method shall be selected first, and then the full compaction construction shall be carried out after completion. Select the rammer component and ramming force according to the reinforcement depth.

满夯压实处理的区域一般是针对整个施工场所，点夯相较而言，仅仅对具体位置强夯，夯点放碎石，经过揉捏土体构成碎石桩。进步修建根底的承载规模。另外在核算的过程中应该考虑夯点间的土层与夯点下的土层之间的负摩阻力。

The area of full compaction treatment is generally for the whole construction site. Compared with point compaction, it is only for dynamic compaction at the specific location. Gravel is placed at the compaction point, and the soil is kneaded to form gravel pile. Improve the bearing scale of the construction foundation. In addition, the negative friction between the soil layer between the tamping points and the soil layer under the tamping points should be considered in the process of accounting.
