A soil profile consists of three in the table Q4. Calculate the equivalent coefficients layers with the properties shown of permeability parallel and normal to the stratum. Table Q4 layer 1 2 3 Thickness z(m) 3.0 4.0 3.0 Kx (parallel, m/s) 2.0×106 5.0×10-8 3.0x10-5 K. (normal, m/s) 1.0×10-6 2.5×10-8 1.5x10-5 II) Water flows through a 100 mm diameter granular soil specimen as shown in figure Q4. The water levels on both sides are maintained constant during the test, and the void ratio of the soil is 0.82, and Gs=2.68. a) What is the maximum possible value for h such that the soil does not reach quick condition? b) For h= 150 mm, 175 ml of water was collected in 15 minutes. Find the permeability of the soil and the effective vertical stress at A 220 mm bel ow the top of the sample. A soil profile consists of three in the table Q4.
