Definition
Meaning and Definition
A geotechnical engineering procedure in which an instrumented probe is pushed into the ground to measure soil properties.
A standardised in-situ test (CPT) used to determine the geotechnical properties of soils and the stratigraphy of subsurface materials by measuring the resistance to penetration of a cone-tipped rod.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both use the same term. Potential minor spelling variations in related documentation (e.g., 'standardise' vs. 'standardize').
Connotations
None beyond the technical meaning.
Frequency
Equally rare and specialised in both dialects, used exclusively within geotechnical engineering, geology, and civil engineering contexts.

Common Mistakes When Using “cone penetration test”
- Using 'cone penetration test' generically for any probe test (it's a specific standard).
- Confusing it with the 'Standard Penetration Test (SPT)', which uses a different sampler and hammer.
FAQ
Frequently Asked Questions
A Cone Penetration Test (CPT) pushes a cone continuously and measures tip resistance and sleeve friction electronically. A Standard Penetration Test (SPT) drives a sampler using a hammer and counts the blows for a specific penetration; it provides a disturbed sample.
Depends on soil strength and equipment, but typical land-based CPTs can reach 30-50 metres. Seabed systems can penetrate up to 50 metres below the seafloor.
A piezocone (CPTu) is an advanced CPT probe that includes a pore pressure sensor to measure the water pressure in the soil pores during penetration, providing additional data on soil type and behaviour.
No, CPT is designed for soils. The cone would be damaged in rock. Rock properties are determined by other methods like core drilling and pressuremeter tests.
A geotechnical engineering procedure in which an instrumented probe is pushed into the ground to measure soil properties.
Cone penetration test is usually technical/specialist in register.
Cone penetration test: in British English it is pronounced /kəʊn pɛnɪˈtreɪʃən tɛst/, and in American English it is pronounced /koʊn ˌpɛnəˈtreɪʃən tɛst/. Tap the audio buttons above to hear it.
