Engineering Manual No. 43: Interpretation of Field Tests into Soil Profiles Using GEO5 Stratigraphy


This forty-third manual in the GEO5 engineering series provides a detailed guide to interpreting field tests and integrating them into soil profiles using the GEO5 Stratigraphy program. The manual covers the process of simplifying and interpreting data from boreholes and other field tests to create accurate geotechnical soil profiles for design and 3D subsoil modeling. Available for download, this manual is essential for geotechnical engineers who need to translate field data into reliable soil profiles for further analysis and modeling.

Learning Objective:

The goal of this manual is to teach users how to interpret and simplify field test data to create geotechnical soil profiles within the GEO5 Stratigraphy program. Users will learn how to work with borehole data, static penetration tests (CPT), and geological sections to define soil layers and create accurate, simplified profiles for geotechnical design and modeling.

Assignment Description:

In this assignment, users are tasked with interpreting field test data from a borehole (BH1) and a CPT test, as previously documented in Engineering Manual No. 42. The interpretation involves simplifying the data into geotechnical soil types, defining soil layer thicknesses, and integrating the information into a soil profile. The manual provides step-by-step instructions for two approaches: interpreting field tests directly within the “Soil Profile” frame and during the creation of geological sections. Users will learn to adjust the profiles by merging layers and assigning geotechnical types to each soil layer.

Outcome:

Upon completing this assignment, users will be able to effectively interpret and simplify field test data into geotechnical soil profiles using GEO5 Stratigraphy. They will gain practical experience in managing field data, creating and editing soil profiles, and integrating these profiles into geological sections for comprehensive 3D subsoil modeling.

Conclusions:

The manual concludes that interpreting field tests into simplified geotechnical soil profiles is a critical step in creating accurate and reliable 3D subsoil models. By following the steps outlined in this manual, users can ensure that their soil profiles reflect the essential characteristics of the subsurface conditions, facilitating better decision-making in geotechnical design and analysis.
