Arching factor for a tieback design

Arching factor for a tieback design

(OP)
Hi fellows, did anybody know a good tieback design manual or textbook for a tieback design, especially the arching factor (values) used for a tieback design? I have a lot of manuals talking about tieback, but none of them ever mentioned the arching factor values (FHWA-RD-75-128,129,130 mentioned it, but no any design values provided).

Manuals I have include: PTI (Recommendations for prestressed rock and soil anchors, post tensioning institute, 1996), the FHWA-RD-82-047 (title: Tiebacks), the FHWA-RD-75-128, 129, 130 (the lateral support systems and underpinning, Volumn I,II, III) and NAVAFAC 7.02.

Thanks fndn. It is a very good manual.

RE: Arching factor for a tieback design

Try:
FHWA-SA-96-038, Geotechnical Engineering Circular No. 2, Earth Retaining Systems

FHWA-IF-99-015, Geotechnical Engineering Circular No. 4, Ground Anchors and Anchored Systems

fndn,

Thanks for that link!  I've been looking for tie-back design information myself..

EXCELLENT!

RE: Arching factor for a tieback design

The Caltrans manual on tiebacks is from 1996.  The FHWA geotechnical circulars are relatively recent, especially with respect to new earth pressure diagrams for tiedback walls.
