The Dutch cone penetration test (DCP), is a versatile sounding method than can be used to estimate soil properties and determine the type of materials. This is also known as the static penetration test. The cone penetration measures the cone resistance (qc) and the frictional resistance (fc) incrementally.
The Dutch Cone Penetrometer Tests (CPT). This test involves forcing a cone into the ground and measuring the rate of pressure needed for each increment of penetration.

(1) Resistance. For the Dutch Cone, resistance to penetration is the sum of point resistance and frictional resistance on the sides of the shaft. The more sophisticated systems can differentiate between the point and frictional components of the resistance, and the ratio between frictional and point resistance (Friction Ratio) is one aid in differentiating between various soil types. Clean sands generally exhibit very low ratios (low friction component in comparison to point resistance), while an increase in clay content will usually result in a higher ratio, more often the result of a reduction in point resistance rather than an increase in frictional component.

(2) Correlations. Correlations have been developed for the cone penetration test with bearing capacity, relative density of sands, strength and sensitivity of clays and over consolidation, as well as with SPT values and pile design parameters
