Soil mechanics - Wikipedia

The aim of this paper is to define the correlation between the geometry of grains and saturated hydraulic conductivity of soils. The analysis was performed on samples of four soils, which were characterised by the same grain size distribution and extremely different particle structure. The shape characteristics varied from ideally spherical, smooth grains glass microbeads GM to highly irregular and rough particles fly ash FA. For each soil, laboratory tests of saturated hydraulic conductivity constant head test CHT and falling head test FHT were performed. Additionally, an empirical analysis of effective pore diameter was conducted with use of the analytical models developed by Pavchich Wolski, and Indraratna and Vafai Experiments have shown that saturated hydraulic conductivity depends on grains shape and surface roughness. This parameter decreases with the increase in the irregularity of soil particles.

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids usually air and water and particles usually clay , silt , sand , and gravel but soil may also contain organic solids and other matter. Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils. Principles of soil mechanics are also used in related disciplines such as engineering geology, geophysical engineering , coastal engineering , agricultural engineering , hydrology and soil physics. This article describes the genesis and composition of soil, the distinction between pore water pressure and inter-granular effective stress , capillary action of fluids in the soil pore spaces, soil classification , seepage and permeability , time dependent change of volume due to squeezing water out of tiny pore spaces, also known as consolidation , shear strength and stiffness of soils. The shear strength of soils is primarily derived from friction between the particles and interlocking, which are very sensitive to the effective stress. The primary mechanism of soil creation is the weathering of rock.
