What it does
The SOE Design Platform locked to soil nail walls: tributary nail loads on total active pressure, tensile and pullout checks with per-row required bond, reinforced shotcrete facing design, nailed-block external checks, Bishop global-stability screening and corrosion allowance.
Features
- FHWA GEC 11 (FHWA-NHI-14-007) ASD method
- Per-row required bond q_u,req vs assumed q_u
- Reinforced shotcrete facing: flexure, shear, plate bearing/bending
- Nailed-block sliding, bearing and overturning
- Bishop slip-circle global stability screening
- Corrosion: sacrificial area + protection-class adequacy
- 13-step branded Word (.docx) and PDF reports
How it works
- Enter soils, nail pattern and bond values
- Review internal, facing and block checks
- Check global stability and corrosion
- Export the 13-step calculation report

Worked example — the FHWA GEC 11 wall, 20 ft
The FHWA worked example ships in the app: a 20 ft soil nail wall with TB #9 (1-1/8-in) Grade 75 bars. Tensile utilisation 0.42, governing-row pullout FS 4.75, block sliding FS 2.68, facing flexure utilisation 0.95, corrosion residual utilisation 0.56, and global stability FS 1.37 against 1.35 required — overall PASS.
Details
