Segmental Retaining Wall Design and Construction

The concept of stabilized earth structures has been around for centuries. Historically, grass mats, straw, and branches have been used to stabilize soil. Now, soil reinforcement utilizes technologically advanced geosynthetic materials to secure earth in retaining walls, bridge abutments, and many other applications. This course reviews the basic concepts about segmental retaining wall systems, focusing on geogrid reinforcement applications, site conditions, and the construction sequence. Key success factors are also discussed.

Upon completion of this course, the Learner should be able to:

• Recall the different features of gravity and stabilized aggregate retaining wall structures, and explain how they are effective and safe soil retention systems.
• Describe the characteristics of reinforced segmental retaining walls (SRWs) and how they are a safe and efficient method of earth stabilization.
• Describe the site conditions that influence reinforced SRW system performance and design, detailing how utilizing geogrid provides a strong and secure soil structure.
• Summarize the overall construction sequence related to reinforced segmental retaining walls.
