Also referenced was Naval Facilities Engineering Comnand, Design Manual 7.2, for flexible wall design. -By varying the number and location of the tieback anchors, the wall design may be optimized for given soil conditions and wall requirements._ xi I CHAPTER 4 - Retaining structures I Andrew J.

Particularly important is the Federal Highway Administration’s (FHWA’s) recent inventory of 3,500 walls for the National Park Service

    This option is limited to block (segmental) walls having simple geometry and using geosynthetic reinforcement (same as the instructions in the NCMA guidelines). The NCMA design procedure, as implemented in MSEW(3.0), is detailed in: Design Manual for Segmental Retaining Walls, 2nd Edition, edited by James C. Collin, 1997. Publication No. TR-127A.
