About The Project

This project is a Streamlit frontend for the PV-tool - a comprehensive Python toolset for geotechnical analysis of soil samples.

PV-tool Integration

The app integrates directly with the PV-tool repository to provide:

• Import & Validation: Load and validate geotechnical data from PV-tool Excel templates
• C-Phi Analysis: Determine cohesion and friction angle parameters (Mohr-Coulomb)
• SHANSEP Analysis: Stress History And Normalized Soil Engineering Properties
• SU Analysis: Undrained shear strength tables and profiles

The PV-tool repository is cloned into pv-tool-submodule/ during installation. See PV-tool Integration Documentation for detailed technical information.

Features

✅ Multi-page Streamlit interface
✅ Full PV-tool integration via wrapper module
✅ Session state management for data sharing
✅ Interactive visualizations with Plotly
✅ Export capabilities (Excel, PDF, CSV)
✅ Support for multiple analysis types and investigation groups

This repository hosts a development version at http://localhost:8501 when running.

Requirements

• Python 3.11
• Streamlit >= 1.39.0
• pandas >= 2.0.0
• numpy >= 1.24.0
• plotly >= 5.18.0
• IDE for development - Visual Studio Code or PyCharm

Installation

1. Clone this repository

git clone https://github.com/your-username/pv-tool-app.git
cd pv-tool-app

2. Clone the PV-tool repository

The PV-tool is integrated as a separate repository in the pv-tool-submodule/ directory:

git clone https://github.com/PVorganization/PV-tool.git pv-tool-submodule

Alternative: Use as git submodule (optional, for advanced users):

git submodule add https://github.com/PVorganization/PV-tool.git pv-tool-submodule
git submodule update --init --recursive

3. Install dependencies

pip install -r requirements.txt

This will install:

• Streamlit and all UI dependencies
• PV-tool dependencies (scipy, matplotlib, openpyxl, etc.)
• Data processing libraries (pandas, numpy)
• Visualization tools (plotly, kaleido)

4. Verify installation

Check if the PV-tool wrapper loads correctly:

python -c "from src.pv_tool_wrapper import pv_tool; print(f'PV-tool available: {pv_tool.available}')"

If you see PV-tool available: True, you're ready to go! 🎉

Run the app

streamlit run app.py

Or use the convenience scripts:

• Windows PowerShell: .\run.ps1
• Windows Command Prompt: run.bat

The app will open in your default browser at http://localhost:8501

Note: The Streamlit server must be running to access the app. If you navigate to http://localhost:8501 and see "This site can't be reached", you need to start the server first using one of the commands above.

Usage

Quick Start

1. Start the server (first time or after reboot):

   streamlit run app.py
   

   Or double-click run.bat or run.ps1

2. Access the app in your browser at http://localhost:8501

3. Stop the server when done: Press Ctrl+C in the terminal

Important: The server needs to be running for the app to be accessible. Think of it like starting a web server - you can't visit a website if the server isn't running!

Available Pages

Once the app runs, you can access the following pages:

1. Home - Landing page with overview of available analyses
2. 📥 Import en Validate - Import and validate geotechnical data from various formats (CSV, Excel, GEF, XML)
3. 📊 C-Phi analyse - Analyze cohesion and friction angle parameters using Mohr-Coulomb failure envelope
4. 🔬 SHANSEP analyse - Stress History And Normalized Soil Engineering Properties analysis
5. 📈 SU-analyse - Undrained shear strength analysis and interpretation

Navigation

• Use the sidebar to navigate between different analysis pages
• Each page includes demo data functionality for testing
• Data flows between pages using Streamlit's session state
• Start with "Import en Validate" to load your data, then proceed to specific analyses

Submodule Issues

If the PV-tool submodule is not properly loaded:

git submodule update --init --recursive

Missing Dependencies

If you encounter import errors:

pip install -r requirements.txt --upgrade

Import Errors

Make sure you're running Python 3.11 and all dependencies are installed:

python --version
pip list
