ABSTRACT
Embedded earth retaining walls commonly comprise vertical structural members of diaphragm walls, secant/contiguous/touch pile walls or sheet pile walls. In engineering practice, these are commonly used for protecting permanent and temporary excavations, for waterfront and transportation structures and for construction of basements and underground infrastructure in urban areas. Due to its narrow base width, this earth retaining structure it is suitable for situations with tight space constraints or right-of-way constraints. Traditionally embedded earth retaining structures are designed based on limit equilibrium analysis. This paper proposes a fast approach for the geotechnical design of both free-standing and singularly propped embedded retaining walls in dry sand. Rankine’s theory for lateral earth pressure is used. The presented dimensionless relationships for estimating the embedment depths are simple, easy to use for any soil conditions (dry and cohesionless) and depths of excavation.
