BS EN ISO 22477-1:2018

This standard BS EN ISO 22477-1:2018 Geotechnical investigation and testing. Testing of geotechnical structures is classified in these ICS categories:

• 93.020 Earthworks. Excavations. Foundation construction. Underground works

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:

1. checking that a pile will behave as designed;

2. measuring the resistance of a pile.
