Title:

Free Fall Penetrometer Data Analysis Application

Free Fall Penetrometers are small devices deployed from boats to measure soil strength and pore pressure. These measurements are analyzed to characterize soil sediment, providing important data for offshore site development. Existing data analysis methods used by ocean researchers lack a graphical user interface, are spread across multiple tools and programming languages, and do not validate user input. Last year's development team produced a desktop application combining all existing data analysis functionality with a graphical interface.​ Expanding upon the application's functionality, calculations were implemented and incorporated into the UI, including the White et al. and Albatal relative density calculations to extend soil classification functionality. These results were then tested against expected outputs from prior analysis to ensure accuracy. Feature development continued in the second semester with the addition of the friction angle calculations. The White et al., Albatal, and Jaber & Stark friction angle calculations were implemented in the UI and verified against the provided outputs. Furthermore, existing MATLAB code was modified and integrated into the application, incorporating pore pressure and tilt calculation features.​ The result provides a more comprehensive application that extends soil classification and pore pressure features while maintaining the application’s efficiency, ease of use, and accuracy.​
