The foundation replacement of dynamic compaction machine is suitable for the equipment group of continuous development, which should be constructed in different ways. It is not suitable to use several kinds of equipment together to stop the cross construction. If they are used together, they will affect each other greatly. The dynamic compaction shall check the test data and construction records of the dynamic compaction construction process. If it does not meet the requirements of the plan, the additional compaction and other useful errors shall be adopted. It is not suitable to use several kinds of equipment together to stop the cross construction. If they are used together, they will affect each other greatly.

选用强夯施工，恳求在作小区翔实决策的竖向计划时，有需要思考强夯的夯沉量影响，因为强夯后园高有所下降。因为强夯法在施工进程傍边，重锤着落时要迸发接连0.50～1s的地基振动。

It is necessary to consider the impact of dynamic compaction on the settlement when making the vertical plan of detailed decision-making for the residential area, because the elevation of the garden has declined after dynamic compaction. Because in the construction process of dynamic compaction method, the foundation vibration will be 0.50 ~ 1s when the heavy hammer falls.

强夯置换其特征是：可使用工地常备简略配备；施工工艺、操纵简略；适合土质限制广，加固成果显赫，可获得较高的承载力，一般地基强度可前进2～5倍；蜷缩性可失落2～10倍，加固影响深度可达6～10m；工效高，施工速率迅速，较换上回填和桩基可收缩工期一半；朴素加固原质料；施工低，朴素出资，比换土回填朴素50%，与预制桩加固地基比拟，可朴素出资50%～70%等。

The features of dynamic compaction replacement are as follows: it can be equipped with simple equipment on site; The construction technology and operation are simple; It is suitable for a wide range of soil restrictions, remarkable reinforcement results and high bearing capacity, and the general foundation strength can advance 2-5 times; The curling property can be reduced by 2-10 times, and the reinforcement depth can reach 6-10m; It has high work efficiency and rapid construction speed, which can shorten the construction period by half compared with the replacement of backfill and pile foundation; Raw materials for simple reinforcement; The construction price is low, and the simple investment is 50% more than that of soil replacement and backfilling. Compared with the precast pile foundation reinforcement, the simple investment is 50% ~ 70%.

强夯地基经由多年的外表及强夯配备的更新，强夯法施工已广泛使用到高速公路铁路，机场、核电站、大工业区靠海等根柢加固工程，并对比较较冗杂的地质如高填方根柢，高含水量根柢，口岸填海根柢，海水吹填根柢等都有成功的施工事例。

After years of renovation of appearance and dynamic compaction equipment, dynamic compaction method has been widely used in highway, railway, airport, nuclear power station, large industrial area and other foundation reinforcement projects, and has successful construction examples for more complicated geology such as high fill foundation, high water content foundation, port reclamation foundation, sea water reclamation foundation, etc.

这种震波对附近必定限制内的设备物(building)是没有毁伤的。但其迸发的杂音对附近住户有必定的影响，以适于制造现场的公害操控值75dB作为标准时，所以施工地址应脱离居处50m之外为宜。

This kind of seismic wave has no damage to the equipment and building within certain limits nearby. However, the noise has a certain impact on the nearby residents. When the pollution control value of 75db suitable for the manufacturing site is taken as the standard, the construction site should be 50m away from the residential area.
