Engineering Manual No. 46: Modeling Earthworks and Calculating Volumes Using GEO5 Stratigraphy


This forty-sixth manual in the GEO5 engineering series guides users through the process of modeling earthworks and calculating volumes using the Earthworks module within GEO5 Stratigraphy. The manual demonstrates how to create subsoil models, model terrain changes, design structures such as terraces and ramps, and calculate the associated earthwork volumes. Available for download, this manual is essential for geotechnical engineers who need to manage and visualize terrain modifications and calculate the volumes of earthworks accurately.

Learning Objective:

The goal of this manual is to teach users how to effectively use the Earthworks module in GEO5 Stratigraphy to model terrain changes, design structures, and calculate earthwork volumes. Users will learn to create subsoil models, model terrain modifications, and integrate these models with other GEO5 programs for further analysis, such as slope stability.

Assignment Description:

In this assignment, users are tasked with creating a pond and a viewing terrace by modeling the subsoil with dimensions of 50×50 meters. The assignment involves modeling terrain changes, designing a terrace with an access ramp, and calculating the earthwork volumes for both excavation and fill. Users will also calculate the volume of water in the pond with a water level 0.4 meters below the edge. The manual provides step-by-step instructions for each stage, including setting up the model, inputting terrain points, and generating cross-sections.

Outcome:

Upon completing this assignment, users will be able to model complex terrain modifications and calculate the associated earthwork volumes using GEO5 Stratigraphy. They will gain practical experience in designing structures such as terraces and ramps, integrating models with other GEO5 programs, and visualizing the results in 3D.

Conclusions:

The manual concludes that the Earthworks module in GEO5 Stratigraphy is a powerful tool for modeling terrain changes and calculating earthwork volumes. By following the steps outlined in the manual, users can accurately model subsoil modifications, calculate volumes for excavation and fill, and design additional structures such as terraces and ramps, ensuring that their projects are planned and executed with precision.
