This thirty-ninth manual in the GEO5 engineering series offers a comprehensive guide to the complete design of a retaining wall made from prefabricated blocks. The manual walks users through every step of the design process, from setting the initial geometry to final verifications, ensuring that the wall meets all necessary standards. Available for download, this manual is essential for geotechnical engineers involved in the design and construction of retaining walls using prefabricated block systems.

Learning Objective:

The goal of this manual is to teach users how to design an entire prefabricated block wall using the GEO5 Prefab Wall program. Users will learn how to input and adjust the geometry, select appropriate block types, apply relevant standards, and perform all necessary verifications to ensure the wall’s stability and structural integrity.

Assignment Description:

In this assignment, users are tasked with designing a retaining wall along a section of the street “Turistická” using prefabricated blocks from the Redi-Rock system. The wall must retain 4 to 3 meters of soil and meet all verifications according to EN 1997, Design Approach 2. The manual provides detailed instructions for setting up the wall’s geometry, selecting and configuring block types, applying load conditions, and performing checks for overturning, sliding, bearing capacity, and overall stability.

Outcome:

Upon completing this assignment, users will be able to design a complete prefabricated block wall using GEO5 software. They will gain practical experience in adjusting block configurations, optimizing wall geometry, and conducting comprehensive stability checks to ensure the wall design meets safety and performance standards.

Conclusions:

The manual concludes that the designed prefabricated block wall, after adjusting the row setback and performing all necessary verifications, meets all stability and structural requirements. The final design successfully retains the soil with a wall consisting of 518 blocks, totaling approximately 514 tons. The documentation includes detailed information about block specifications, weights, and volumes, which are crucial for project planning and material management.
