This application performs axial capacity analysis for a variety of deep foundation types in stratified soil profiles. The calculations are adapted from the NAVFAC Foundations & Earth Structures Design Manual 7.02, last edited September 1986. This tool allows users to input a custom soil profile with several layers, select a foundation type and installation type, and input a selection of foundation widths and bearing depths to analyze simultaneously.
After submitting an analysis, the user will be presented with a collection of summary tables showing the ultimate and allowable axial capacity of each foundation in compression and in tension. Beyond the summary tables, the user can view a detailed output for each individual pile showing the results of each calculation. The results may be saved in PDF form, and users can save their projects to enable tweaking the input parameters. Additionally, users can clone projects so they can easily analyze different pile types without needing to input the soil data again.
Calculations are performed based on established soil science and the NAVFAC Foundations & Earth Structures Design Manual 7.02, last edited September 1986. This manual is available to download for free here.
Any engineer who uses this tool is expected to understand the NAVFAC analysis process as a prerequite and to review the calculations for accuracy. The author of this program takes no responsibility for any engineering decisions made by anybody using this application. Use it at your own risk.
