Where V_v is the volume of the voids (empty or filled with fluid), and V is the total volume of the soil. Porosity is usually used in parallel with soil void ratio (e) , which is defined as the ratio of ... WebPoorly graded soils are either uniformly graded or gap-graded. [3] A poorly graded gravel is classified as GP while a poorly graded sand is classified as SP. Poorly graded soils are more susceptible to soil liquefaction than well graded soils.
