For coarse grained soil, the particle size D10 is sometimes called as ...
Introduction:
Coarse-grained soils are soils that contain a high percentage of large particles. These particles are typically categorized based on their size distribution, with the D10 (10th percentile) being an important parameter in characterizing the soil.
Explanation:
The particle size D10 is sometimes referred to as the effective size or effective diameter of the soil particles. This term is used because the D10 value represents the size below which 10% of the soil particles are smaller. In other words, it is the size at which 10% of the soil particles are finer.
Importance of D10:
The D10 value is an important parameter in soil mechanics and geotechnical engineering. It is used to classify soils and determine their engineering properties. The D10 value is particularly useful in analyzing the behavior of coarse-grained soils, such as sands and gravels.
Effective size:
The term "effective size" refers to the size of a particle that would have the same settling velocity as the soil particles being analyzed. It is an indicator of the hydraulic conductivity and permeability of the soil. The effective size can be determined by performing sedimentation tests or using particle size analysis techniques.
Effective diameter:
The term "effective diameter" is another way of expressing the effective size of the soil particles. It is the diameter of a hypothetical sphere that has the same settling velocity as the soil particles. The effective diameter is also used to calculate the coefficient of uniformity (Cu) and coefficient of curvature (Cc) of the soil gradation.
Conclusion:
In summary, the particle size D10 is sometimes referred to as the effective size or effective diameter of coarse-grained soils. It represents the size below which 10% of the soil particles are finer. The effective size and effective diameter are important parameters in characterizing the hydraulic conductivity and permeability of the soil. They are used to classify soils and determine their engineering properties.
