simple retaining wall calculations

(c)Tall retaining walls. As the wall height increase it become less feasible to use the simple construction shown in Figure 1(b) or (c). The overturning moment increases sharply with the increase in height of the wall. For very tall walls one modification used is to taper the wall thickness. This permits the

Cantilever concrete retaining walls are commonly used for residential purposes, often as integral basement walls. Usually the software such as Mathcad or Excel will be useful for design iterations. The example calculations are made here using Mathcad. 1.2 Example Wall. Figure X.2. Concrete cantilever wall example.

provided of the design of a simple cantilever retaining wall, following BS8002. It is shown how to construct been to eliminate the various safety factors against sliding, overturning, etc., , which were used in CP2 (19502, The aim of this paper is to set out these newfstyle calculations so as to demonstrate their ease of use.

Basic calculations needed to design a retaining wall!

Retaining walls. Example 3.16 Design of a cantilever retaining wall (BS 8110). The cantilever retaining wall shown below is backfilled with granular 144 76. 92 34 . . = 1.56 > 1.5 OK. OVERTURNING. Taking moments about point A (see above), sum of overturning moments (Mover) is. FA. kNm. ×. = ×. =.

Retaining Walls. Page 14. Solution: Step 1: Calculate lateral soil pressure and overturning moment. P max = Ka γsoil h = 0.33 (110)(12) = 435.6 psf. FH = ½ Pmax h = ½ (435.6)(12)= 2613.6 lb ft of wall. Sliding Force, FH = 2613.6 lb ft of wall. Overturning Moment, MOT about toe = 2613.6 x 4 = 10454.4 lb-ft ft of wall. 12'. 2'. 2'.

This manual presents the techniques used by Allan Block in our engineering practice to design retaining walls. It is not intended as a textbook of soil mechanics design of geogrid reinforced retaining walls. Design calculations alone cannot ensure that designs will yield a safe ..
