| Summary |
"Slopes of all kinds, including mountains, hills, sea coast bluffs, river banks, and man made cuts and fills, stay in place only because of the shearing strength possessed by the soil or rock of which they are composed. The resistance of soils to shearing strength is probably the most important of all the soil properties to foundation engineers. Most of the serious structural failures which are due to unexpected soil behaviour are caused by deficiency in the shearing strength of the soil. Water, on the other hand, possesses no static strength in shear, therefore bodies of water have no surface relief. If shearing stresses in a body of soil exceed the shearing strength, the soil fails. Failure depends on the conditions of soil support and loading. The failure may cause a slide, the collapse of a retaining wall, or the settling of a footing into the ground. From this, it can be seen that determination of the shearing strength of soils is of primary importance to the engineer, especially to the foundation engineer"--Introduction, leaf 1. |
