Theories of lateral earth pressure will be used in this chapter to design various types of retaining walls. In general, retaining walls can be divided into two major categories: A- Conventional retaining walls B- Mechanically stabilized earth walls dr. isam jardaneh / foundation engineering 61303 / 2010

There are two phases in the design of a conventional wall: First: Geotechnical Design (External Stability) With the lateral earth pressure known, the structure as whole is checked for external stability, which are overturning, sliding, bearing capacity failures and overall Failure. dr. isam jardaneh / foundation engineering 61303 / 2010

Second: Structural Design (Internal Stability) Each component is checked for strength (thickness). The steel reinforcement of each component is determined. dr. isam jardaneh / foundation engineering 61303 / 2010
