Recommendations for Prestressed Rock and Soil Anchors

active, Most Current
Organization: PTI
Publication Date: 1 January 2014
Status: active
Page Count: 120
scope:

These Recommendations provide practical guidance in the application of permanent and temporary prestressed rock and soil anchors using high-strength prestressing steel. They represent the current state of practice and provide recommendation for the design, installation, and testing of grouted prestressed rock and soil anchors, but are not necessarily applicable to other anchor systems.

Due to the broad nature of these Recommendations, particular sections shall be clearly referenced when included in the specifications for a specific project.

These Recommendations contain significant revisions and supersede PTI DC35.1-04. The revisions enhance the consistency of the recommendations and provide additional guidance in many subjects, including:

• Special prestressing materials

• Corrosion protection

• Drilling methods

• Water pressure testing

• Sheath repair

• Grouting

• Creep testing

• Resin anchors (Supplement B)

A list of the standard specifications and references cited throughout this document can be found in Section 9.2 The values stated in either Sl units or in.-lb units are to be regarded as standard. Within the text, the in.-lb units are shown in brackets.

The values stated in each system are not exact equivalents, and so each system must be used independently of the other.

These Recommendations were prepared by PTI Committee DC-35, Prestressed Rock and Soil Anchors, with input and review by the ADSC - International Association of Foundation Drilling Anchored Earth Retention Committee.
