Grouted anchors may be defined as structural elements capable of transmitting an applied tensile load from a structure to a load-bearing stratum, and the nature of their construction necessitates that large portions of the structural elements are hidden from sight. As a consequence of this, the condition of these hidden structural elements is not subject to an easy appraisal.
Soil nailing is a technique where either natural ground or fill material is reinforced by the insertion of slender tension-carrying elements called soil nails. A soil-nailed slope or wall usually consists of the soil nails themselves, a hard, flexible or soft facing to the slope or wall surface, and surface water and sub-surface drainage systems. Soil nailing has become a relatively common method of slope stabilisation and retention.
This project is to prepare needed guidance in the form of a report that will use case histories, published material and industry experiences to describe good practices and recommendations to assessing the condition and providing remediation to grouted anchors and soil nails.
This new guidance will be of significant interest to asset owners, engineers and other stakeholders and it will include:
- Cross referencing to relevant, supportive literature and guidance
- Case histories and evidence of system failures
- Visual inspection techniques
- Monitoring techniques
- Non-intrusive investigations
- Intrusive investigations
- Maintenance and repair
- Relevant case studies and examples
