Which soil property does the Dynamic Cone Penetrometer primarily measure?

The Dynamic Cone Penetrometer measures how strongly soil resists penetration, which is a direct reflection of its shear strength. As the cone is driven into the ground by repeated hammer blows, the penetration rate or blows per unit depth increases with weaker soils and decreases with stronger, stiffer soils. This penetration resistance is then used as an index of soil shear strength, and through correlations it informs about bearing capacity. It is not a direct measurement of maximum flexural strength, nor a direct measure of compaction resistance, and while it can be related to load-bearing capacity, its primary focus is the soil’s ability to resist shear.
