Figure 15.8. Scope of EN 1537, Execution of... ground anchors

Test type Purpose is to...

Investigation establish resistance at grout/ground interface critical creep load of anchor system, or creep characteristics up to failure load, or load loss characteristic at SLS apparent tendon free length

Investigation establish resistance at grout/ground interface critical creep load of anchor system, or creep characteristics up to failure load, or load loss characteristic at SLS apparent tendon free length

Suitability

confirm for ability to sustain the proof load design situation creep or load loss up to proof load apparent tendon free length

Acceptance

confirm for each ability to sustain the proof load anchor creep or load loss at SLS, where necessary apparent tendon free length

EN 1537 describes three different test methods for ground anchors, summarized below.
