Abstract
The electrical cone penetration test (CPT) consists of pushing a cone penetrometer using a series of push rods into the soil at a constant rate of penetration. During penetration, measurements of cone resistance and sleeve friction are recorded. The piezocone penetration test (CPTU) also includes the measurement of pore pressures around the cone. The test results may be used for interpretation of stratification, classification of soil type and evaluation of engineering soil parameters. There are two standards about cone penetration tests: EN-ISO 22476-1 describes CPT and CPTU practice using electronic transducers; EN ISO 22476 12 describes CPT practice using mechanical measuring systems.
This document deals with equipment requirements, the execution of and reporting on electrical cone and piezocone penetration tests as part of geotechnical investigation and testing according to EN 1997 1 and EN 1997 2.
The test results of this document are specially suited for the qualitative and/ or quantitative determination of a soil profile together with direct investigations (e.g. sampling according to prEN ISO 22475-1) or as a relative comparison of other in situ tests.
