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 [...]

In this article we will discuss about the characteristics and factors affecting the sheer strength of sand. Shear Strength Characteristics of Sand: Shear strength characteristics of sandy soils depend on the drainage conditions in addition to several other parameters as discussed in the following subsections. 1. Shear Strength Characteristics of Saturated Sands during Drained Shear: It is nearly impossible to [...]
