ABSTRACT
Example 11.3 For the earth retaining structure shown in Fig. Ex. 11.3, construct the earth pressure diagram for the active state and determine the total thrust per unit length of the wall.
Solution
1-sin 30° 1 K - --A-I+ sin 30° - 3
Dry unit weight yd = GsYw = 2.65 x 62.4 = 100.22 Ibl ft 3 l+e 1+0.65
Figure Ex. 11.3
2.65-1 _ 3 1+ 0.65 x 62.4 - 62.4 lb/ft
Assuming the soil above the water table is dry, [Refer to Fig. Ex. 11.3(b)].
