What is the impact of the thickness of the soil layer on soil compaction?
Soil must be filled and compacted in layers; only after each layer meets the required degree of compaction can another layer be added. The thickness of each layer and the desired degree of compaction are determined according to the standards of different industries and their specific requirements. For example, in the case of highway embankments with a thickness of 3 meters, it is generally required that each layer have a thickness of 0.5 meters and that the degree of compaction reach 0.97. If 3 meters of soil are filled at once and then compacted, it will be difficult to compact the bottom layer. The depth to which compaction takes effect depends on the compaction energy, and this depth is limited. Over time, uneven consolidation occurs, resulting in uneven surfaces.

The main factors affecting soil compaction: ★★ These mainly include the type of soil being compacted, the amount of compaction effort applied, the moisture content of the soil, as well as the thickness of each layer of soil applied and the number of compaction passes. I feel that the thicker it is laid, the thicker the entire foundation will be after compaction, and vice versa. Last edited by Lailai on 2009-3-20 16:45]
