Ground Anchors - TA 2020

Résumé

The present document replaces the recommendations called « Tirants d’Ancrage (TA) 95 », which were written by a working group under the auspices of the Comité Français de la Mécanique des Sols et des Travaux de Fondation (French Committee of Soil Mechanics and Foundation Works*, which was the denomination of CFMS at the time). In line with the previous issues, it aims at addressing all aspects pertaining to the execution of ground anchors: design, construction, monitoring and maintenance. Through a decision notified on January 24 2020, the C2P biannual publication of July 2020 will record the approval by the C2P of the new edition of the text. It will also be made available on the AQC website. It is based upon three different types of standards (execution, justification and testing), which it aims at synthesising for France. Note : using the present rules within other countries compels to verify beforehand that these countries use the same frame of reference than France. As such, the present document can be used autonomously and independently from standards in most frequent cases. However, if the standards are ones that have to be applied mandatorily (it is the case for Government procurement) and/or contractual ones, one should check beforehand that the normative references have not evolved beyond the present edition. The Developer, or its Project Manager, shall state whether he wants to keep the original text, or if he wants to revise the paragraph(s) concerned by the standard update.1 Note : decision was taken to write this document as a stand- alone one, and hence, several paragraphs mention excerpts of current standards without stating them comprehensively. The hypotheses which the drafters of the technical body relied upon (which the present document is a part of), are reminded below : • Data required for design are collected, recorded and inter- preted by appropriately qualified and experienced personnel; • Structures are designed by a personnel with the appropriate skill and experience; • Adequate continuity and communication exist between the personnel involved in data-collection, design, verification and execution; • An appropriate monitoring and quality control system is in place in factories, design offices, companies and on the field; • The execution of works is carried out in accordance with the standards and their associated specifications by a personnel with the appropriate skill and experience; • The construction materials and products are used in accor- dance with the specifications of the present document, or with the specifications specific to the materials or products being used; • The structure is properly maintained, so that its stability and serviceability are guaranteed during its whole lifetime; • The structure is adequately monitored in order to detect in advance any abnormal behaviour; • The structure is used in accordance with the objectives defined when it was designed.
