In this publication, h set out to explain important discoveries he had made. Sme of the significant concepts covered in this publication include: “onsolidation theory, sttlement calculations, baring capacity theory, lteral earth pressures and retaining walls, sear strength and slope stability” (EJGE 1). Te classical theory of one-dimensional consolidation was developed by Karl von Terzaghi. H came up with this theory after undertaking studies on effective stress principle. Te theory was derived after making ideal assumptions. H developed this theory in 1925. Tis theory states that: Adecrease of water of a saturated soil without replacement of the water by air is called a process of consolidation – Saturated clay soils of low permeability, wen subjected to a comprehensive stress or surcharge, imediately experiences an increase in the pore water pressure.
I is the time lag between the application of the load and the dissipation of excess pore water pressure which leads to settlement, wich takes place over a long period of time. (aculty of Civil Engineering 1)The soil is homogenous and full saturated; Te compressible of both soil and water is negligible; Te problem is one-dimensional with respect to both soil strains and the movement of water; Drcy’s law applies, wth a constant coefficient of permeability within any load increment; Te relationship between void ratio and effective stress is linear within any load increment, ad independent of time; te total stress is constant and layer thickness does not change appreciably during a load increment.
(aculty of Civil Engineering 1)The classical theory of one-dimensional consolidation has been very significant in modern applications of geotechnical engineering. Athough it has modified to be more practical, te contribution of Karl von Terzaghi cannot be overlooked.
Te significance of the theories that Karl von Terzaghi developed is that they have formed the foundation upon which concepts of modern geotechnical engineering is based. Te classical theory of one-dimensional consolidation, fr instance, i very significant in modern geotechnical engineering applications. Te theory has remained to be the foundation of engineering practices (Faculty of Civil Engineering 1). Tis theory has been expanded and modified and applied in...
