Reduced anchor wall capacity
Reduced anchor wall capacity
(OP)
I am designing a sheet pile retaining wall that will utilize a continuous sheet pile anchor wall. The wall is being constructed along an existing sloped roadway embankment to facilitate widening of the road and the anchor wall will be located under the existing roadway. There are some site constraints, though, that may require that a portion of the anchor wall to be placed inside the minimum spacing required for full mobilization of the resisting pressure. Is there an accepted method for calculating the reduced capacity of the anchor wall? I've seen references to procedures by Terzaghi but have been unable to put my hands on anything! Any input is appreciated.

Good Luck.

Check out FHWA Geotechnical Engineering Circular No. 2, Earth Retaining Systems (FHWA-SA-96-038) and Geotechnical Engineering Circular No. 3, Ground Anchors and Anchored Systems (FHWA-IF-99-015).
Pile Buck's manual is the old US Steel Sheet Piling Design Manual. It is geared toward bulkheads with triangular soil pressures. Nowadays, most tiedback walls, especially highway walls, are soldier beam and lagging walls, tiedback as necessary, with precast or cast-in-place concrete facings. In the USA, highway walls must be designed for AASHTO criteria.
