The publication of BS EN 1537:2013 “Execution of special geotechnical works – grouted anchors”, the revision of BS8081 and the current work to revise EC7, presents a timely opportunity to review current methods of inspection, monitoring, testing and maintenance of grouted anchors and produce good practice guidance for the industry.
Many structures in the UK and abroad rely on grouted (ground) anchors for permanent structural support, Typical examples of these include:
- retaining walls
- deep excavations
- bridge abutments
- transmission towers
- buoyant structures
Grouted anchors have been used commercially since 1934 and have been subject to continual advancements in design, execution and sustainability. It is not easy to inspect or maintain the condition of ‘hidden’ structural elements. But, anchor failure could lead to loss of support to the structure, resulting in unacceptable deformations, and in the worst case, structural collapse.
CIRIA and the UK’s leading infrastructure owners and operators will work together to develop good practice guidance on the condition appraisal and remedial measures to be applied to those structures affected.
This project will incorporate guidelines on condition monitoring and assessment processes that can be used for the classification of grouted anchors in service, as well as the risk strategies to be adopted as part of their sustainable maintenance / management.
