DYWIDAG Soil Nail Anchor System
Soil Nail Testing
Soil nail testing is performed to establish the bond capacity within the stable zone of a slope. Tests performed, can include:
- Ultimate tests (sacrificial) where nails are tested until failure occurs
- Proof tests can be performed on sacrificial or production nails
- Creep tests are generally conducted during a proof or sacrificial testing to determine long term nail movement and/or load loss. Acceptance criteria should be based on allowable movements of the wall over its life span
- Test load is measured with a pressure gauge calibrated with the hydraulic jacking system. Nail movement is recorded by a dial gauge mounted on an independent stand.
