http://www.ce.memphis.edu/1101/notes/filtration/sieve_analysis.pdf WebA soil mass also consists of a number of interconnected voids that act as capillary tubes of varying diameter. And because of the capillary effect water in the soil rises above the water table in these voids up to some height. The water present in the soil pores below the water table is in compression and pore water pressure is positive.

Please notice that the permeability scale is in units of x10-4 cm/sec. So a graph result of 1.0 is actually 1.0x10-4 cm/sec and a graph result of 100 is actually 100x10-4 cm/sec (1 ... WebMay 31, 2024 · The uniformity coefficient (Cu) is defined as the ratio of D60 to D10. A value of Cu greater than 4 to 6 classifies the soil as well graded. When Cu is less than 4, it is classified as poorly graded or uniformly graded soil. Uniformly graded soil has identical particles with Cu value approximately equal to 1.
