In the design of free-standing retaining walls, the following aspects need to be investigated: However, as the wall becomes really tall, it is often necessary to consider the use of various bracing technique, as shown in Figure 2.įigure 2:- Tall Retaining Walls Retaining Wall Design Considerations This permits the development of a reasonable cross section for the high bending stress at the base without an excessive amount of concrete.

The overturning moment increases sharply with the increase in height of the wall.įor very tall walls one modification used is to taper the wall thickness. The form of such a key is shown in Figure 1(c)įigure 1:- Retaining Structure (c) Tall retaining wallsĪs the wall height increase it become less feasible to use the simple construction shown in Figure 1(b) or (c). When the bottom of the footing is a show distance below grade on the low side of the wall and/or the lateral passive resistance of the soil is low, it may be necessary to use an extension below the footing – called a shear key – to increase the resistance to sliding.

these consists of a concrete or masonry wall of uniform thickness, vertical wall reinforcing, and transverse footing reinforcing are all designed for the lateral shear and cantilever bending movement plus the vertical weights of the wall, footing, and earth fills. Vertical walls up to about 3m in height are usually built as shown in Figure 1(b). Use of these structure is typically limited to grade level changes of about 0.6m or less. The two most common forms are as shown in Figure 1(a), the selection being made on the basis of whether or not it is necessary to have a gutter on the how side of the curb. The range of its dimensions establishes some different categories for the retaining structure as follow:Ĭurbs are the shortest freestanding retaining structures.
