A triaxial test is conducted on a soil sample which was consolidated under a cell pressure of 550 kN/m² with a back pressure of 250 kN/m². Thereafter drainage was not allowed and cell pressure was raised to 675 kN/m² with pore water pressure reading of 360 kN/m.². After that the axial load is increased by 455 kN/m2, and corresponding pore water pressure reading is 575 kN/m². The Skempton's parameter A is (Round off to two decimal places).

Q: The constant-head permeability test arrangement in a two-layered soil has been arranged as shown in Figure. During the test, it was seen that when a constant head of h₁= 220 mm was maintained, the magnitude of h2 was 70 n If ki is 0.005 cm/sec, determine the value of k2. (given that H₁-120 mm and H₂= 160 mm). h₁ Soil 1 (ky) ►1 Soil 2 (k₂) Water supply T h TT H₁ H₂ ©ⒸCengage Learning 2014
