References used include Design Manual for Segmental Retaining Walls,2.1 Edition,and Segmental Retaining Walls-Seismic Design Manual, 1st Edition,both by <br /> NCMA. <br /> 2. Blocks are all same size and uniform offsets(batter)for full wall height. <br /> 3. Coulomb earth pressure theory used for earth pressures and failure plane angle. <br /> 4. Refer to geotechnical report for backfill material,compaction,and other design data and recommendations. <br /> 5. Cap blocks if used are above the retained height and are neglected in this design. <br /> 6. Geogrid LTDS and connection values for block vendors obtained from ICC Evaluation Service(ES Legacy Reports)or as provided by vendors.Since these may <br /> change or be updated,verification of values is recommended. <br /> 7. Block sizes obtained from vendors'literature and may vary with locality. <br /> 8. Geogrid layers are equally spaced vertically,all same length,and laid horizontally. <br /> 9. Average weight of block and cell infill assumed to be 120 pcf. <br /> 10. See vendor web sites(on input screen)for more information and specifications. <br /> 11. Design height is limited to 16 feet or 24 blocks,whichever is less. Contact vendor for higher designs or special conditions. <br /> 12. Seismic design is per Seismic Design Manual cited above. Also see Methodology/Seismic Design in User's Manual. <br /> 13. Vendor specifications or project specifications,whichever is most restrictive,to be followed for construction procedures. <br /> 14. Add notes and details for proper drainage. <br /> 15. See User's Manual Design Example#10 for methodology and sample verification calculations. <br /> 16. Final design responsibility is with the project Engineer-of-Record. <br /> ( 1, <br />
