This is a combination of two book for two different types of retaining walls. For tall, flexible anchored tieback walls: In practice, the procedures used to design flexible tieback
wall systems differ from those used to design stiff tieback wall systems. In the design of flexible tieback wall systems, apparent pressure diagrams are commonly used to represent the maximum loads the tieback wall system might experience during construction. Apparent pressure diagrams used in an equivalent beam on rigid supports analysis are demonstrated in this report. Analyses are performed for flexible wall systems in both cohesionless and clay soil. For tall, stiff tieback walls: Methods used in the design of flexible and stiff tieback walls are described. Methods applicable to the design of stiff tieback wall systems are illustrated by example. Important in the design of stiff tieback wall systems is the consideration of construction sequencing effects.
