DIN EN ISO 22476-1:2013-10 EN ISO 22476-1:2012 + AC:2013 (E) 4Introduction The electrical cone penetration test (CPT) consists of pushing a cone pene

34、trometer 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 can be u

35、sed for interpretation of stratification, classification of soil type and evaluation of engineering soil parameters. Two International Standards define cone penetration tests: ISO 22476-1 defines CPT and CPTU practice using electronic transducers; ISO 22476-12 defines CPT practice using mechanical m

36、easuring systems. “Cone resistance” is the term used in practice and in this part of ISO 22476, although “cone penetration resistance” is a more correct description of the process. The test results of this part of ISO 22476 are specially suited for the qualitative and/or quantitative determination o

37、f a soil profile together with direct investigations (e.g. sampling according to ISO 22475-1 2) or as a relative comparison of other in situ tests. The results from a cone penetration test are used to evaluate: stratification; soil type; geotechnical parameters such as soil density, shear strength p

38、arameters, and deformation and consolidation characteristics. DIN EN ISO 22476-1:2013-10 EN ISO 22476-1:2012 + AC:2013 (E) 5 1 Scope This part of ISO 22476 deals with equipment requirements, the execution of and reporting on electrical cone and piezocone penetration tests. NOTE 1 This part of ISO 22

39、476 fulfills the requirements for electrical cone and piezocone penetration tests as part of geotechnical investigation and testing according to EN 1997-1 3 and EN 1997-2 4. Within the electrical cone and piezocone penetration test, two subcategories of the cone penetration test are considered: elec

40、trical cone penetration test (CPT), which includes measurement of cone resistance and sleeve friction; piezocone test (CPTU), which is a cone penetration test with the additional measurement of pore pressure. The CPTU is performed like a CPT with the measurement of the pore pressure at one or severa

41、l locations on the penetrometer surface. NOTE 2 CPT or CPTU can also be used without measurement of sleeve friction, but this is not covered in this part of ISO 22476. This part of ISO 22476 specifies the following features: a) type of cone penetration test, according to Table 1; b) application clas

42、s, according to Table 2; c) penetration length or penetration depth; d) elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum; e) location of the cone penetration test relative to a reproducible fixed location referenc

43、e point; f) pore pressure dissipation tests. NOTE 3 This part of ISO 22476 covers onshore and nearshore CPT. For extra requirements for offshore CPT, see NORSOK G-001 8.

NOTE 2 This part of ISO 22476 assumes that the cone is rigid, so when loaded its deformation is very small relative to the deformation of other parts of the cone penetrometer. 3.1.3 cone penetration test CPT pushing of a cone penetrometer at the end of a series of cylindrical push rods into the ground at a constant rate of penetration 3.1.4 cone penetrometer assembly containing the cone, friction sleeve, any other sensors and measuring systems as well as the connection to the push ro
