In this article we will discuss about how to determine the shear strength of soil. Shear Tests: The shear strength parameters (c, ɸ) are determined under definite test conditions. Depending upon the drainage conditions, three types of shear tests have been developed. They are: (i) Unconsolidated undrained test (or simply undrained test) UU- No drainage of pore water is allowed [...]
The following are the various types of tests available for the determination of shear strength: 1. Direct Shear Test 2. Triaxial Compression Test. 3. Unconfined Compression (UCC) Test. 4. Vane Shear Test. 5. Bore Hole Shear Test. 1. Direct Shear Test: Direct shear test is a simple and commonly used test performed in a shear box to determine the shear [...]
