For typical cohesive or cohesionless soils it has been observed that the soil shear stress (‫ )ح‬varies as the soil strains or deforms during soil shearing. Soil strength was altered in three different ways to test the hypothesis that soil splash from raindrop impact is related to soil strength parameters. … Of many factors affecting shear strength of soils directly or indirectly, density, effective stress and soil structure are the most important (Terzaghi et al., 1996). The soil shear strength is a measure of its resistance to deformation by continuous displacement of its individual soil particles. In the first part, the stiffness of soil at small strain level (γ≈10-6) is analysed. Factors Affecting Soil Shear Strength The shear strength of a soil is achieved by interaction between the solid, liquid, and gas particles in its make-up. TEST PROGRAM AND PROCEDURE 15. For clays having a high sensitivity, such as quick clays, disturbance can severely affect the shear strength. Strength of different materials Steel Tensile strength Concrete Compressive strength Soil Shear strength Presence of pore water Complex behavior 3. The best way to obtain the shear strength of a soil is to measure it directly by laboratory test or in situ test and by reproducing in the test the same stress conditions as those anticipated in the field. Shear failure occurs when the stresses between the particles are such that they slide over each other. • Interlocking of solid particles to resist deformation. Percolation Test Procedures.
