Overview
Scope
This manual defines the technical scope of the application and the function of each document route:
- CPT interpretation: reconstruction, classification, layer derivation, and parameter assignment from the CPT trace.
- Stage 6 engineering analyses: model definition, governing equations, reported outputs, and boundaries of validity for each analysis module.
- Methods: notation, constitutive conventions, governing equations, discretization choices, and numerical procedures.
- References: standards context, literature basis, quantity definitions, export fields, symbols, and units.
- Technical specification: complete implementation detail for audit, review, and verification.
