The walls are infilled with granular soil with or without reinforcement while retaining the backfill soil.
Segmental concrete reinforced soil retaining walls.
Identify the different features of gravity and stabilized aggregate retaining wall structures and explain how they are effective and safe soil retention systems.
Segmental retaining walls can be designed as either conventional or as reinforced soil as illustrated in figure 1.
Segmental retaining walls consist of modular concrete blocks that interlock with each other.
Soil reinforced segmental retaining walls.
Soil reinforced srws are composite systems consisting of srw units in combination with a mass of reinforced soil.
Describe the characteristics of reinforced segmental retaining walls srws and how they are a safe and efficient method of earth stabilization.
The soil is stabilized by horizontal layers of reinforcement typically a geosynthetic material.
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.
Without adequate retention slopes can cave slump or slide.
Manufacturer s recommendations should be followed regarding the capacity of their particular system for the soil loads under consideration.
Geogrid reinforced soil walls.
The wall face is often of precast segmental blocks panels or geocells that can tolerate some differential movement.
The reinforced soil mass along with the facing.
The structural capacity of the srw system will vary with the srw unit size shape batter etc.
