Design and Performance of a Retaining Wall

Case study: Design and performance of the MSE wall of 46 m in height and purpose of the retaining wall measurement Seattle - Tacoma International Airport (STIA) is located in SeaTac, Washington State. Due to severe weather conditions, the distance between existing runways is limited, so the airport needs to be expanded. Therefore, the third runway was built on the west side of the existing two runways. The third runway embankment building consists of three MSE walls. The following are three MSE walls. In this study, the monolayer 58 feet high-south MSE wall vertical double layer 85 feet high north wall vertical 4 layers 150 feet high west MSE wall, the third runway is the building

The retaining wall is a stable structure designed and constructed to hold the soil in a slope larger than the naturally assumed slope, usually in a vertical or nearly vertical position. In addition, retaining walls are used to prevent soil erosion and migration. The role of the retaining wall is to resist the lateral pressure of the soil, and if the necessary change in the height of the ground surface exceeds the natural inclination used in the soil, it is called the repose angle of the soil. The retaining wall is a soil wedge on the upper plane of the angle of repose that the retaining wall must support.

Evaluate the design of the retaining wall to reduce the effect of the landslide. Retaining walls help protect soil from the various movements associated with these natural disasters. Considering the dangers of landslides and the risk of liquefaction, the water saturation of the earth is part of evaluating how the retaining wall functions. The cantilever retaining wall is composed of walls of uniform thickness connected to the foundation. It is in the basement of the bungalow. Therefore, the cantilever retaining wall blocks the earth. Soil erosion, landslides, environmental disasters are unlikely to occur. In other words, rupture and collapse of 20 unit luxury bungalows were avoided.

As mentioned above, the cantilever retaining wall is a set of masonry that holds a large amount of soil in place. Cantilever beam design is only one of several variations in retaining wall design and uses various principles for managing the load on the ground. The economical height range of cantilever retaining wall is 200 - 6.000 m. This type of retaining wall is adequate for bungalows because it has enough height to support the bungalows. Concrete cantilever retaining wall is made of relatively thin steel, field striking, concrete or plaster. In the cantilever retaining wall design, the earth pressure vector acts horizontally on the side of the wall. The bottom of the wall represents the gravity vector. This gravity vector creates upward opposing force. The resulting vector is for the Earth's pressure vector and is pushed back against the ground load.
