Description (English):

This document establishes the specifications for the execution of static pile load tests in which a single pile is subjected to an axial static load in compression in order to define its load-displacement behaviour. This document is applicable to vertical piles as well as raking piles. All types of piles are covered by this document. The tests considered in this document are limited to maintained load tests. Pile load tests with constant penetration rate and cyclic load tests are not covered by this document. NOTE This document is intended to be used in conjunction with EN 1997-1. EN 1997-1 provides numerical values of partial factors for limit states and of correlation factors to derive characteristic values from static pile load tests to be taken into account in design. This document provides specifications for the execution of static axial pile load tests: a) checking that a pile will behave as designed; b) measuring the resistance of a pile.

Abstract

Overview

EN ISO 22477-1:2018 - Geotechnical investigation and testing - Part 1: Testing of piles: static compression load testing - specifies how to perform static axial compression (maintained) pile load tests to determine a pile’s load–displacement behaviour and compressive resistance. The standard applies to vertical and raking piles and to all pile types, but it excludes constant-penetration-rate and cyclic load tests. It is intended to be used in conjunction with EN 1997-1 (Eurocode 7) for deriving design values and partial factors from test results.

Key topics and technical requirements

Scope and purpose: Defines objectives - checking that a pile behaves as designed and measuring its resistance.
Equipment and setup:
- Reaction devices and reaction system requirements.
- Force-input systems (jacks, hydraulic systems) and calibration requirements (referencing ISO 7500-1 for force-measuring verification).
- Instruments for measuring pile head displacement and load (including pile instrumentation options).
Test procedure:
- Test preparation (protection, test pile construction and pile-cap preparation).
- Loading procedures: maintained load tests with specified load step sequences, durations and measuring intervals; provisions for single- and multiple-cycle procedures.
- Definition of maximum test load and guidance on measuring intervals and data acquisition.
Data handling and reporting:
- Mandatory content of test reports: general information, detailed data records and an interpretative report with conclusions on measured resistance and behaviour.
Annexes:
- Informative guidance on critical creep load in compression and bi-directional load testing.

Applications and practical value

Provides standardized methods for static pile load testing, ensuring consistent, reliable measurement of pile capacity and settlement behaviour.
Enables:
- Validation of pile performance against design assumptions.
- Derivation of characteristic pile resistance values for foundation design (used with Eurocode 7).
- Quality assurance and acceptance testing on construction projects.
Typical uses include deep foundation verification for buildings, bridges, offshore structures and infrastructure where accurate pile capacity assessment is required.

Who should use this standard

Geotechnical and foundation engineers performing or specifying pile load tests.
Testing contractors and site technicians responsible for executing maintained static load tests.
Structural engineers integrating pile test results into design per EN 1997-1.
Consultants, laboratories and regulatory bodies involved in geotechnical investigation and construction quality control.
