What are 3 engineering applications of the coefficient of permeability of soils (what phase of
construction, purpose of them and the importance they hold to geotechnical engineers)
Solution
The permeability of soils is a very important feature which plays the crucial role in issues
connected with the flow of ground water and the migration of pollutions. The occurrence of
subsoil water in a building-site often complicates realization of works and requires an additional
intervention with the use of special equipment. The ability of water conduction in a soil is the
essential factor in the consolidation process because it decides about the intensivity of this
phenomenon. The realization of structural constructions is, almost in every case, directly or
indirectly connected with the flow of subsoil water. Thus the problem of water flow in soils has
been the subject of scientific research for many years.
Factors Affecting Permeability of Soil
Studying soil permeability is important because of the following reasons:
1. Underground seepage study is an important aspect of all the Civil Engineering works because
once a foundation is laid, you don\'t want the soil mass holding your foundation to leak water.
2. It aids in the determination of geostatic stresses and the effect of water pressure on earth
structures.
3. It gives a beforehand idea about settlement of a foundation and volumetric changes in soil
layers when subjected to fluids or water.
4. Before constructing a structure, it is always helpful to know the amount of water that can be
discharged through a soil mass, and calculating permeability is the best way to know the
discharge quantity.
There are numerous factors that affect the permeability of a soil mass. Important factors are
mentioned below:
1. Chemical components of the interacting fluid, if not water, and its temperature.
2. Porosity of the soil mass under consideration, soil compaction also impacts permeability of
soil.
3. Permeability from particle size of soil grain size, particle shape, and degree of packing of soil
mass constituents.
Cohesive soils deserve particular attention with regard to their low permeability. For a long time,
these soils have been used to build cores of earth dams and constructions protecting hydro-
engineering structures against harmful results of seepage. Natural or remould structure layers of
cohesive soils are a good isolating material to be built-in. Therefore, they can successfully fulfil
the role of seepage barriers protecting the environment against the expansion of pollution.
