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 [...]
Shear strength characteristics of clays unconsolidated undrained conditions are discussed below for normally consolidated clays and pre-consolidated clays. 1. Normally Consolidated Clays: After consolidation under cell pressure is complete, no excess pore water pressure is present inside the sample. However, when the specimen is subjected to the subsequent increase of axial stress, under undrained conditions, an increase in excess pore [...]
