This fifth manual in the GEO5 engineering series focuses on the design and analysis of anchored retaining walls. Using the GEO5 software, this guide walks you through each step necessary to design a retaining wall with one row of anchors, ensuring stability and safety under various conditions. This manual, now available for download, is an essential resource for geotechnical engineers seeking to refine their skills in anchored retaining wall design.

Learning Objective:

The objective of this manual is to equip users with the knowledge and skills to design an anchored retaining wall using the EN 1997-1 (EC 7-1, DA3) standard. Users will learn to perform stability analyses, cross-section verifications, and optimize the design by comparing different wall support conditions.

Assignment Description:

The assignment involves designing an anchored retaining wall using sheet pile type VL 602, focusing on a ditch with a depth of 5.0 meters. Users will analyze the wall’s performance with one row of anchors, considering both hinged and fixed support conditions at the heel. The manual provides detailed guidance on setting up the model, determining acting pressures, performing analyses, and verifying the design’s stability.

Outcome:

Upon completing the assignment, users will be able to design an anchored retaining wall that meets all necessary safety and stability requirements. They will gain practical experience in using GEO5 software to evaluate different design scenarios and make informed decisions about the most efficient and effective design solutions.

Conclusions:

The manual concludes that the designed anchored retaining wall, using sheet pile type VL 602 and S 240 GP steel, meets all required stability and safety standards. The chosen design, with a 3.7-meter embedment depth and anchors with a 400 kN force, is optimized for material efficiency while ensuring structural integrity. The analysis results confirm that the wall is suitable for the given conditions, and further verification can be performed using the “Sheeting Check” program.
