Segmental retaining walls consist of modular concrete blocks that interlock with each other.
Segmental concrete reinforced soil retaining walls.
They are used to hold back a sloping face of soil to provide a solid vertical front.
Soil reinforced srws are composite systems consisting of srw units in combination with a mass of reinforced soil.
Without adequate retention slopes can cave slump or slide.
The reinforcement increases the effective width and weight of the gravity system.
Reinforced walls utilize horizontal layers typically of geogrids.
Identify the different features of gravity and stabilized aggregate retaining wall structures and explain how they are effective and safe soil retention systems.
Manufacturer s recommendations should be followed regarding the capacity of their particular system for the soil loads under consideration.
Describe the characteristics of reinforced segmental retaining walls srws and how they are a safe and efficient method of earth stabilization.
Segmental retaining walls can be designed as either conventional or as reinforced soil as illustrated in figure 1.

Geogrid reinforced walls are gravity retaining walls with an expanded width commonly known as reinforced fill zone created by the placement of geogrid behind a column of segmental facing units.
The walls are infilled with granular soil with or without reinforcement while retaining the backfill soil.
The wall face is often of precast segmental blocks panels or geocells that can tolerate some differential movement.
