Not illustrated. 1912 Excerpt: ...of repose, f, the angle of surcharge, 8, and the angle that the resultant thrust makes with a normal to the back of the wall, z. For any particular case, K will be a constant and the unit pressure at any point will vary as the height h. In Fig. 181 the resultant pressure, P, is rep resented by the area of the shaded triangles, and the center of pressure will be at J/t from the base, the same as for fluid pressure. Stability of Retaining Walls.--A retaining wall must be stable ( i ) against overturning, (2) against sliding, and (3) against crushing the masonry or the foundation. The factor of safety of a retaining wall is the ratio of the weight of a filling having the same angle of internal friction that will just cause failure to the actual weight of the filling For a factor of safety of 2 the wall would just be on the point of failure with a filling weighing twice that for which the wall is built. 1. Overturning.--In Fig. 182, let P, represented by OP', be the resultant pressure of the earth, and W, represented by Olf, be the weight of the wall acting through its center of gravity. Then E, represented by OR, will be the resultant pressure tending to overturn the wall. Draw OS through the point A. For this condition the wall will be just on the point of overturning, and the factor of safety against overturning will be unity. The factor of safety for = 07? will be.f0=sir/Rir (98) 2. Sliding.--In Fig. 182 construct the angle HiG equal to f, ', the angle of friction of the masonry on the foundation. Now if E passes through 1, and takes the direction OQ, the wall will be on the point of sliding, and the factor of safety against sliding, /, . will be unity. For E = OR, the factor of safety against sliding will be (990) Retaining walls seldom fail by slidi...
