For fully saturated soil, degree of saturation is
0
1
5
none of the above
1
Degree of saturation (SrтАЛ) is defined as the ratio of the volume of water to the volume of voids in a soil sample. For a fully saturated soil, all voids are filled with water, making the volume of water equal to the volume of voids, resulting in SrтАЛ=1 (or 100%).
Degree of saturation (SrтАЛ) is defined as the ratio of the volume of water to the volume of voids in a soil sample. For a fully saturated soil, all voids are filled with water, making the volume of water equal to the volume of voids, resulting in SrтАЛ=1 (or 100%).
SrтАЛ=VvтАЛVwтАЛтАЛ тАФ where VwтАЛ is volume of water and VvтАЛ is total volume of voids.
SrтАЛ├Чe=w├ЧG тАФ relationship between degree of saturation, void ratio (e), water content (w), and specific gravity (G).
Soil is a three-phase system consisting of solids, water, and air. In a fully saturated condition, the air phase is completely displaced by water, meaning the volume of air VaтАЛ=0. Consequently, the volume of voids VvтАЛ is entirely occupied by water VwтАЛ, leading to the ratio VwтАЛ/VvтАЛ=1.
Degree of saturation ranges from 0 (dry soil) to 1 (fully saturated soil).
It is a dimensionless property often expressed as a percentage.
If 0<SrтАЛ<1, the soil is considered partially saturated.
Used to identify the drainage condition of soil.
Essential parameter for calculating unit weights and effective stress.
Geotechnical site investigations.
Analysis of soil compaction and earthwork construction.
A value of SrтАЛ=0 implies a perfectly dry soil.
The range of SrтАЛ is 0тЙдSrтАЛтЙд1.
B is correct тАФ For fully saturated soil, the volume of water equals the volume of voids, making the degree of saturation equal to 1.
Remember the fundamental relationship SrтАЛe=wG to quickly solve problems involving phase properties, as it is a frequent point of calculation in GATE and ESE exams.
