Dynamic compaction method is a mature foundation reinforcement technology recognized after years of practice. It is widely used in foundation treatment of various sites. However, there will inevitably be some buildings around some sites. What kind of impact will the foundation treatment by dynamic compaction have on these buildings?
In general, the influence of foundation treatment by dynamic compaction on buildings is not only related to the construction parameters related to dynamic compaction construction, but also closely related to the properties of soil and the structure of buildings.
Due to the huge tamping energy produced by dynamic compaction construction, the tamping point will generally drop rapidly. At the same time, the soil layer at the tamping point will swell. The deformation of the foundation is bound to have an adverse impact on the surrounding buildings.
During dynamic compaction construction, when the rammer falls, it will produce a form of earthquake due to vibration, because the falling of the rammer will produce very large vibration wave. As the seismic wave spreads around, it will cause the deformation of soil structure and direct impact on buildings, and the deformation of soil will indirectly threaten buildings.
To sum up, dynamic compaction construction will have different degrees of impact on the surrounding soil and buildings.
