Abstract
There are different methods to retain soil cuts or support vertical sides of soil embankments. Traditional methods are simply different types of typical retaining walls, such as, gravity retaining walls, semi-gravity retaining walls, cantilever retaining walls, counterfort retaining walls, etc. However, new modern trends are now available for these projects and the most common one is soil reinforcement. It is simply based on reinforcing the soil by horizontal strong intrusion made by steel or geosynthetic materials. This system is first suggested by Vidal in the 60’s of the last century. The system specialized for supporting soil vertical cuts is called Mechanically Stabilized Earth Retaining Wall and mainly composed of facing elements, reinforcing bars and backfill soils.
The aim of this project is to design mechanically stabilized earth retaining walls for different heights and compare this design with traditional retaining walls, such as, cantilever retaining walls which the most common types in our region. Finally, comparisons will be made between the two types of retaining walls from economical and time of construction point of views.
Chapter Two summarizes the mains aspects of soil reinforcement It talks about how to increase the pressure-bearing capacity of soil, what is its working principle and types0
Chapter Three It talks about the types of traditional retaining walls, the characteristics of each wall, and the heights that each wall can reach
Chapter Four It presents the main idea of mechanically stabilized earth retaining walls, what are its components, uses, and how to build it.
Chapter five We designed the (MSERW) wall in four different conditions and four different heights: 8, 10, 14, and 18 heights.
Chapter six We designed the Traditional wall in four different conditions and four different heights: 8, 10, 14, and 18 heights.
Chapter seven We made cost and practical comparisons and presented the results.
