DESIGN STANDARDS FOR RETENTION WALLS
To ensure the safety of the project as well as contribute to limiting landslides, construction units need to master the standards for designing retaining walls. So how are the standards for designing retaining walls regulated? Let's find the answer with Hung Nghiep Phu in the article below!
1. What is a retaining wall?
Before learning about the design standards of retaining walls, you need to understand the concept of retaining walls.
Retaining walls are walls built to block soil, minimizing landslides.
Retaining walls are considered to be an absolutely rigid structure, practically immobile, if the following conditions are met: under the effect of the calculated force, when determining the malleability of the wall itself, the deformability of the wall foundation causes the displacement of the back of the wall to be equal to or less than 1/5,000 of the height of the wall section under consideration from the top of the foundation to the calculated cross-section.
In construction and water transport, earth retaining walls have the effect of keeping the embankment or the excavation from sliding. Retaining walls are classified based on many factors such as soil hardness, height, wall angle or wall structure. Each type will be suitable for a separate project.
However, reinforced concrete earth retaining walls are more commonly used because of their good load-bearing capacity, high durability and long-term economic efficiency.
2. How are the design standards for retaining walls regulated?
The design standards for retaining walls are specified in the following main points:
- The design standards for retaining walls are a measure to evaluate the quality of the project before it is handed over for use. These standards are built based on design drawings and documents related to the terrain and topography.
- The design standards for retaining walls are determined based on indicators of sliding stability; overturning stability of the retaining wall and conditions to ensure the bearing capacity of the foundation soil.
- In the case of retaining wall foundations placed on the foundation: soil or rock with high intensity, low risk of damage due to deep sliding instability; mixed sliding, it is necessary to check 2 factors of overturning surface and sliding surface; effects of horizontal force ...
- Retaining walls: ensure design standards and technical requirements; will help promote the effectiveness of soil protection, ensure safety for the project; and contribute to limiting landslides.

3. Calculation of retaining walls and impact pressure
Earth retaining walls are built to block the earth, so when constructing; the construction unit needs to calculate the earth pressure acting on the retaining wall. The factors that need to be known when calculating earth retaining walls are the cohesion values c, c0,,φ, φ0. This is a factor that greatly affects the active pressure of the soil on the retaining wall. The slope angle of the soil roof behind the retaining wall β also contributes to increasing the value of the soil pressure on the wall.
You need to note that:
- The cohesion values c, c0,,φ, φ0 ; have a great influence on the active pressure of the soil on the retaining wall.
- The slope angle of the soil roof behind the retaining wall β increases the value of the active pressure.
- Ecd (α>0) > Ecd (α=0) > Ecd (α<0)
Therefore, when designing standard retaining walls, in addition to choosing the type of retaining wall; The height of the retaining wall needs to be carefully considered; the physical and mechanical index values of the soil behind the embankment.
4. Benefits of Complying with Retaining Wall Design Standards
- Safety and durability: Compliance with standards helps ensure the safety of the structure and the durability and stability of the retaining wall.
- Construction performance: Standards help optimize the performance of the structure, ensuring the accuracy and efficiency of the retaining wall.
- Saving resources: Determining appropriate materials and design techniques helps save resources and reduce waste.
- Protecting the environment: Considering the impact of the structure on the environment and applying measures to protect the surrounding environment.
- Compliance with laws and regulations: Meeting the legal and regulatory requirements of the country or region on the design of retaining walls.
Earth retaining wall design standards play an important role in ensuring the safety, quality and performance of the project. Compliance with these regulations helps to build earth retaining walls that are stable, durable and reliable. At the same time, compliance also ensures that the construction meets the requirements of safety, environmental protection and legal compliance.
