The shear strength of the soil is an important factor to consider in designing structures that bear loads on or in the ground. However, there are several limitations associated with relying solely on shear strength ... WebThe term was introduced by Karl von Terzaghi also known as the "father of soil mechanics and geotechnical engineering". Terzaghi established the one-dimensional consolidation theory and changed the definition of the term since it was previously associated (and still is, in geosciences) with the compaction of clay sediments that formed shales. WebJan 1, 2014 · The soil shrinkage is defined as the specific volume change of soil relative to its water content and is mainly due to clay swelling properties (Haines, 1923; Stirk, 1954 ). It can be measured in most soils with more than 10% clay content (Boivin et al., 2006) and shows a typical S-shape (Figure 1 ). is bt speed test accurate
