Geotechnical investigation and testing - Testing of geotechnical structures - Part 6: Load testing of soil nails and rock bolts (ISO 22477-6:2026); German version EN ISO 22477-6:2026
Abstract
This document establishes the specifications for the execution of tension tests to be carried out on soil nails and rock bolts. This document provides specifications for three types of tension tests: investigation tests, suitability tests and acceptance tests. Two methods of testing are recognised by this document. Test Method A involves step-loaded maintained load tension tests. Test Method B involves constant displacement rate tension tests. This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and the presentation of the test results and the content of records, aiming at: a) measuring the pull-out resistance of a soil nail or a rock bolt; b) checking that a soil nail or rock bolt behaves as designed.
