Dalah San Beta Submission

Team Members

• Irene Peng

Challenge Theme

Direct Design/Interpretation: Develop tools that use DIGGS data for engineering analysis, design recommendations, or automated interpretations.

Project Description

Dalah San is a geotechnical engineering web application that integrates DIGGS XML data into practical engineering workflows. The project focuses on transforming DIGGS-structured subsurface data into engineering calculations, design checks, and interpretation-ready outputs for field and design decisions.

Current completed modules used for submission:

• Liquefaction analysis
• Shallow foundation analysis
• Deep excavation safety checks (uplift and sand boil)

The application includes DIGGS import/processing, engineering parameter handling, calculation pipelines, and result visualization to support applied geotechnical practice.

Technologies Used

• Python
• Flask
• NumPy
• Pandas
• Matplotlib
• OpenPyXL / XlsxWriter
• HTML/CSS/JavaScript
• DIGGS XML data model
