Open-source geotechnical engineering application for analyzing laterally loaded piles, modeled after the industry-standard L-Pile program.

🚀 Live Demo: (https://mjamiv.github.io/pile-designer/)

• Non-linear pile analysis using P-Y curve methods
• Finite difference solver with Newton-Raphson iteration
• Client-side computation via Pyodide (Python in browser)
• Interactive visualization of results
• Open source and free to use

• Frontend: React + TypeScript + Vite
• Computation: Pyodide (Python + NumPy/SciPy in WebAssembly)
• Visualization: Plotly.js (planned)
• Deployment: GitHub Pages

• Node.js 18+
• npm

Laterally loaded piles are analyzed using the beam-column equation:

EI · d⁴y/dx⁴ + P · d²y/dx² + p(y) = 0

Where:

• y(x) = lateral deflection at depth x
• EI = flexural rigidity
• P = axial load
• p(y) = soil reaction (from P-Y curves)

• Finite Difference Method: Discretize pile into nodes
• Newton-Raphson Iteration: Solve non-linear system
• P-Y Curves: Matlock (soft clay), Reese (stiff clay), API (sand)

• Project setup and basic UI
• Pyodide integration
• Basic finite difference solver
• Full P-Y curve implementations
• Interactive Plotly charts
• Soil profile builder
• Multiple load cases
• PDF report generation
• GROUP analysis (pile groups)
