References used include Design Manual for Segments/ Retaining Walls, 2"" Edition, and Segmental Retaining Walls -Seismic Design Manual, 1st Edition, both by NCMA. 2. Blocks are all same size and uniform offsets (batter) for full wall height. 3. Coulomb earth pressure theory used for earth pressures and failure plane angle. 4. Refer to geotechnlcal report for backfill material, compaction, and other design data and recommendations. 5. Cap blocks If used are above the retained height and are neglected In this design. 6. Geogrid L TDS and connection values for block vendors obtained from ICC Evaluation Service (ES Legacy Reports) or as provided by vendors. Since these may change or be updated, verification of values Is recommended. 7. Block sizes obtained from vendors' literature and may vary with locality. B. Geogrld layers are equally spaced vertically, all same length, and laid horizontally. 9. Average weight of block and cell infill assumed to be 120 pcf. 1 o. See vendor web sites (on input screen) for more lnfonnation and specifications. 11. Design height is limited to 16 feet or 24 blocks, whichever is less. Contact vendor for higher designs or special conditions. 12. Seismic design Is per Seismic Design Manual cited above. Also see Methodology/Seismic Design In User's Manual. 13. Vendor specifications or project specifications, whichever is most restrictive, to be followed for construction procedures. 14. Add notes and details for proper drainage. 15. See User's Manual Design Example #10 for methodology and sample verification calculations. 16. Final design responsibility Is with the project Engineer-of-Record.
