The main advantages of the dynamic compaction method include: wide applicability, significant reinforcement effects, large effective reinforcement depth, simple construction equipment, material and cost savings, and environmental friendliness.

(1) Application Scope: Compaction method can be used to reinforce various sandy soils, silt soils, general clay soils, loess, artificial fill soils, especially suitable for reinforcing large aggregate soils that are difficult to reinforce by general methods, as well as mixed fill soils composed of shallow, domestic waste, or industrial waste. The replacement method can also be used to reinforce soft soil foundations.

(2) Enhanced Reinforcement Effect: After being treated with dynamic compaction, the foundation soil's shear strength and bearing capacity can be significantly improved, while its compressibility is reduced.

(3) Construction equipment is simple: The main equipment for dynamic compaction is crawler cranes. Auxiliary dynamic compaction machines may be used in necessary cases, such as with gantry frames and other facilities, to enhance lifting capacity and stability.

(4) Material Savings: Compared to other foundation treatment methods, the dynamic compaction method does not require steel, cement, and other construction materials, significantly reducing the consumption of construction materials.

(5) Cost Savings: The dynamic compaction method is cost-effective compared to commonly used ground treatment technologies, being only 1/6th of the cost for CFG piles, 1/10th for mixed piles, and 1/2 for lime-soil piles.

(6) Eco-Friendly: The dynamic compaction method does not consume materials like steel and cement, which are high-energy consumers, and it does not pollute the surrounding environment.

The main drawback of the dynamic compaction method is that it generates significant vibration and noise during construction, which can affect the surrounding buildings, structures, and environment.

The dynamic compaction method is suitable for treating foundations such as crushed soil, sandy soil, low-saturation silt and clay, collapsible loess, unconsolidated fill, and mixed fill. The treated foundation not only enhances the strength of the soil but also reduces its compressibility, while also improving its resistance to vibration-induced liquefaction. Therefore, dynamic compaction is often used for treating foundations with liquefiable sandy soil as well.

The dynamic compaction method is simple to operate, has a wide range of soil applicability, and provides significant reinforcement effects. It can achieve higher bearing capacity, typically increasing the ground strength by 2 to 5 times; it reduces settlement and compressibility by 2 to 10 times; the soil particles are tightly bound, offering high structural strength; it is highly efficient with rapid construction speed, cutting the construction period in half compared to soil replacement and backfilling; it conserves reinforcement materials; has low construction costs, saving investment; it saves 60% of the costs compared to soil replacement and backfilling, and up to 50% to 70% compared to precast pile reinforcement, and 40% to 50% compared to sand piles.
