Title: Post-Tensioning Institute (PTI) Technical Note 14: Recommendations for Prestressed Rock and Soil Anchors

PTI Technical Note 14 provides recommendations for the design, fabrication, installation, and testing of prestressed rock and soil anchors. These recommendations aim to ensure proper performance, durability, and reliability of the anchoring systems used in various applications like retaining walls, dam foundations, slope stabilization, and excavation support.

Key aspects of the recommendations include:

  1. Design: The design process should consider factors such as the anchor type, size, and capacity, as well as the geological and environmental conditions of the site. It should also account for load factors, anchor spacing, and corrosion protection.

  2. Materials: Anchor components like high-strength steel bars or strands, corrosion protection materials, and grout should meet specific requirements to ensure quality and durability.

  3. Fabrication: Fabrication processes should include proper handling and storage of materials, as well as appropriate procedures for cutting, threading, and welding of anchor components.

  4. Installation: Anchor installation should be carried out by qualified personnel following specific procedures, including drilling, cleaning, and grouting of anchor holes, and the placement of anchor components.

  5. Stressing and testing: Prestressing of anchors should be done using appropriate equipment and procedures. Testing methods, such as proof and performance tests, should be conducted to verify the anchor's capacity and performance.

  6. Monitoring and maintenance: Regular inspection and monitoring of installed anchors should be performed to ensure their continued performance and durability. Maintenance activities should be carried out as needed, based on the monitoring results.
