Cone penetration test - Wikipedia

The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy.It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch cone test".

Static penetration test (CPT) & piezocone (CPTu)

CPT/CPTu static tests are used for the precise recognition of the characteristics of the subsoil.

Use of CPT for design, monitoring, and performance ...

(CPTU) can be used during all phases of a soil compaction project. On most soil compaction projects, the critical design consideration is total and differential settlement. However, settlement analyses are often still based on over-simplified empirical methods that often are quite unreliable.


The CPTWD in its simplest form consists of a piezocone mounted in a core barrel so that the CPTU tip remains under the "shoe" of the drilling casing for at least 30 or 50 cm. For example, if ...

CPT (Cone Penetration Testing) | Geoprobe Systems® - CPT Test

CPT test primary measurements include tip resistance(qc), sleeve friction(fs), and pore pressure(u). Tip resistance is a measurement of soil hardness, sleeve friction is an indication of the soil cohesive strength commonly seen with clays and pore pressure is related to the pressure generated as the cone is advanced as well as an indication to the amount of clay in the formation.
