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 tension 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. Cyclic load tests are not covered by this document. NOTE ISO 22477-2 is intended to be used in conjunction with EN 1997-1. 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 are provided in EN 1997-1. This document provides specifications for the execution of static axial pile load tests: a) checking that a pile behaves as designed, b) measuring the resistance of a pile.
Abstract
Overview
ISO 22477-2:2023 - "Geotechnical investigation and testing - Testing of geotechnical structures - Part 2: Testing of piles: Static tension load testing" specifies how to perform static axial tension (uplift) load tests on a single pile to determine its load–displacement behaviour and tensile resistance. The standard covers vertical and raking piles of all types and is limited to maintained (static) load tests; cyclic tests are excluded. ISO 22477-2 is intended to be used in conjunction with EN 1997‑1 for design factors and correlations.
Key topics and technical requirements
- Scope and purpose: Defines procedures to check that a pile behaves as designed and to measure pile resistance (tensile resistance at the ultimate limit state).
- Equipment and reaction systems:
- Reaction devices may include shallow foundations or compression piles; embedded jacks (see ISO 22477‑1) are recognized.
- Minimum clear distances between test pile and reaction system are specified to limit interference (e.g., guidance on 5D over‑estimation limit, 10D recommended for serviceability; for piles
