Q
What is poorly graded
A
Poorly graded soil refers to a sedimentary soil sample that displays only one or a few of the numerous possible grain sizes
For instance, a poorly graded sand (SP) may only contain fine and medium grains of sand but not coarse grains.
In contrast, a well-graded sand (SW) includes fine, medium, and coarse grains of sand.
Poorly graded soils are more susceptible to soil liquefaction than well-graded soils.
These soils have a limited range of particle sizes, leading to a lack of uniformity in their composition and significant void spaces between particles, which affects their engineering properties such as strength and compressibility.
