“…Within this range of variation of Poisson's ratio, researchers came to certain conclusions about porosity and saturated soil. These conclusions state that: melting at pores increases Poisson's ratio (Mann and Fatt, 1960); porosity decreases while Poisson's ratio increases (Koefoed et al, 1963); for saturated soils, Poisson's ratio is 0.45 and greater (Bowles, 1982); the ratio is close to 0.5 for high bulk modulus (low compressibility) of water-saturated soils (Bishop and Hight, 1977); it is above 0.49 for clayey water-saturated shallow sediments (Stuempel et al, 1984). On the other hand, Poisson's ratio and V p /V s ratio are approximately 0.1 (Gregory, 1976) and 1.5 (Tatham, 1982), respectively, for sediments saturated with gas.…”
