Geotechnical investigation and testing - Testing of geotechnical structures - Part 5: Testing of anchorages (ISO/DIS 22477-5:2009) prEN ISO 22477-5

Scope

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.
