Assumptions

Vertical cantilever sheet pile wall; level ground both sides
Two-layer soil: top frictional (Rankine Ka/Kp), lower undrained clay (total stress)
Passive reduction factor r_p applied to passive only
Active in clay uses tension cut-off: σ_a=max(0, γz−2c_u)
Numerical integration about dredge line (no iteration to solve D)
Seismic (optional): Ka replaced by Kae for frictional layer; clay unchanged (simplified)

Tip: Next steps for a full sheet pile design usually include max bending moment, deflection/serviceability, groundwater effects, staged excavation, and section selection (Z / EI).
