CEN/TC 341/WG 4 - Testing of geotechnical structures

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.

This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of displacement at the load stages; Test Method 2 involves cyclic tension loading with measurement of load loss at the load stages; and Test Method 3 involves step-loading with measurement of displacement under successive maintained tension loads.
This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and presentation of the test results and the content of records.
NOTE       This document does not provide specification for the size of the proof load and the limiting criteria. These aspects reside in EN 1997-1 or its national annex for CEN countries and in similar national application documents for this test standard for ISO countries.

This Standard establishes specifications for the execution of tension load tests where an anchor grouted in the ground, as defined in EN 1997-1, is loaded by step (method 3) or in incremental cycles (methods 1 and 2) from a datum load to a maximum test load. The displacement of the anchor head is measured over a period of time at each step (method 3) or at maximum load in each incremental cycle (method 1). The loss of load is measured over a period of time, at maximum load after lock off, in each incremental cycle (method 2).
This standard provides specifications for three types of tension tests: investigation tests, suitability tests and acceptance tests.

This Standard 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. The provisions of EN 22477-1 apply to vertical piles as well as raking piles. All types of piles are covered by this standard. The tests considered in this Standard are limited to maintained load tests.
EN 22477-1 shall 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. Guidance on
analysis of the load testing results is given in the informative Annex D.
This Standard provides specifications for:
a) Investigation tests, whereby the pile is loaded up to failure or close to failure ;
b) Control tests, whereby the pile is loaded up to a specified load in excess of the SLS
design action.
