Geotechnical investigation and testing — Testing of geotechnical structures — Part 6: Testing of soil nails and rock bolts

Scope

This Standard establishes specifications for the execution of tension tests to be carried out on soil nails, as defined in EN 14490.The standard provides specifications for two types of tension tests as defined in EN 14490: tests to failure and creep tests.NOTE Investigation tests are performed on sacrificial nails and normally include tests to failure and creep tests. Suitability tests are performed on production nails and are usually creep tests.Two methods of testing are recognised by this Standard. Method A involves step-loaded maintained load tension tests, enabling both failure and creep testing. Method B involves constant rate pull-out tests to failure.The standard provides specifications for the experimental devices, the measurement system, the test procedures, the definition and the presentation of the test results and the content of records.The provisions of this standard shall be applied to all types of nails.
