This eleventh manual in the GEO5 engineering series focuses on the analysis of soil consolidation under a constructed embankment. Utilizing the GEO5 Settlement program, this guide walks users through the process of modeling consolidation over time, including primary and secondary consolidation effects. Available for download, this manual is an essential resource for geotechnical engineers who need to assess settlement over different time intervals in soil subjected to external loads.

Learning Objective:

The goal of this manual is to teach users how to perform a consolidation analysis under an embankment using GEO5 software. Users will learn how to model the construction stages, input soil parameters, and calculate the settlement over specified time intervals to ensure the stability and performance of the embankment.

Assignment Description:

In this assignment, users are tasked with determining the settlement value under the center of an embankment constructed on impermeable clay, one year and ten years after its construction. The analysis includes defining the soil layers, assigning the embankment as a surcharge, and performing consolidation calculations using the CSN 73 1001 standards. The manual provides detailed steps for each stage of construction, from initial geostatic stress to long-term settlement.

Outcome:

Upon completing this assignment, users will be able to accurately model and analyze the consolidation of soil under an embankment, ensuring that the design meets the necessary criteria for stability and serviceability over time. They will gain practical experience in using GEO5 to simulate the effects of long-term loading on soil and to predict settlement at various stages of construction.

Conclusions:

The manual concludes that the embankment settlement under its center within one year from its construction is 84.5 mm, and after ten years, it is 282.5 mm. These results highlight the importance of considering long-term consolidation in geotechnical design, ensuring that the embankment performs as expected throughout its lifecycle.
