The dynamic compaction machine leasing company reminds: when using the dynamic compaction machine for construction, the foundation will have settlement, and the determination of settlement is very important. Therefore, we should determine the elevation of the starting surface of the site according to the settlement value behind the site foundation and the leveling design elevation of the ground after compaction. The ground leveling elevation after tamping shall be determined according to the use requirements of the site and the earthwork balance during foundation pit excavation. It should be more than 0.5m higher than the base design elevation and 0m ~ 0.8m lower than the outdoor floor design elevation. Several standards shall be paid attention to at the same time to ensure the safe operation of dynamic compaction.

1、按地基变形设计或应作变形验算且需进行地基处理的工程，应对处理后的地基进行变形验算。

1. For projects designed according to foundation deformation or requiring deformation checking calculation and foundation treatment, the deformation checking calculation shall be carried out for the treated foundation.

2、受较大水平荷载或位于斜坡上的工程，当建造在处理后的地基上时，应进行地基稳定性验算。

2. For projects subject to large horizontal loads or located on slopes, when they are built on the treated foundation, the foundation stability checking calculation shall be carried out.

3、施工过程中应有专人或专门机构负责工程监理，施工结束后必须按本规程规定或有关规定进行施工质量检验和验收。

3. During construction, special personnel or special institutions shall be responsible for project supervision. After construction, construction quality inspection and acceptance must be carried out in accordance with the provisions of this specification or relevant national regulations.

4、复合地基载荷试验应符合现行标准的有关规定。

4. The load test of composite foundation shall comply with the relevant provisions of the current national standards.

5、对需进行地基变形计算的工程，经强夯地基处理后应进行地基沉降观测，并符合现行标准的有关规定。

5. For the project requiring foundation deformation calculation, the foundation settlement observation shall be carried out after dynamic compaction foundation treatment, and shall comply with the relevant provisions of the current national standards.
