30、t of ISO 22477 outlines how a rapid load pile test is defined and specifies the equipment and testing procedures required. Informative, non-prescriptive guidance is included on the analysis of rapid load pile test results required to determine mobilised or ultimate compressive resistance of a pile.D

31、IN EN ISO 22477-10:2017-01EN ISO 22477-10:2016 (E) 5 1 ScopeThis part of ISO 22477 establishes the specifications for the execution of rapid load pile tests in which a single pile is subject to an axial load in compression to measure its load-displacement behaviour under rapid loading and to allow a

32、n assessment of its measured compressive resistance (Rc,m) and corresponding load-displacement behaviour.This part of ISO 22477 is applicable to piles loaded axially in compression.All pile types mentioned in EN 1536, EN 12699 and EN 14199 are covered by this part of ISO 22477.The tests in this part

33、 of ISO 22477 are limited to rapid load pile tests only.NOTE 1 This part of ISO 22477 can be used in conjunction with EN 19971. Numerical values of partial factors for limit states from pile load tests to be taken into account in design are provided in EN 19971. For design to EN 19971, the results f

34、rom rapid load pile testing will be considered equivalent to the measured compressive resistance, Rc,m, after being subject to appropriate analysis.NOTE 2 Guidance on analysis of the rapid load testing results to determine measured compressive resistance and corresponding load-displacement behaviour

35、 is given in Annex A.This part of ISO 22477 provides specifications for the following:a) investigation tests, whereby a sacrificial test pile is loaded up to ultimate limit state;b) control tests, whereby the pile is loaded up to a specified load in excess of the serviceability limit state.NOTE 3 Ge

36、nerally, an investigation test focuses on general knowledge of a pile type; a control test focuses on one specific application of a pile.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document
