The following compression readings were taken during an oedometer test on a saturated clay specimen (G. -2.73) when the applied pressure was increased from 214 to 429kPa: TABLE G Time (min) 0 1 2 16 25 Gauge (mm) 5.00 4.67 4.62 4.53 4.41 4.28 4.01 3.75 3.49 Time (min) 36 49 64 81 100 200 400 1440 Gauge (mm) 3.28 3.15 3.06 3.00 2.96 2.84 2.76 2.61 After 1440 min, the thickness of the specimen was 13.60mm and the water content was 35.9%. Detennine the coefficient of consolidation from both the log time and the root time methods and the values of the three compression ratios. Determine also the value of the coefficient of permeability. Q7 (b) Give a detailed (with sketches) practical field solution to accelerate the rate of consolidation. (c) Give a detailed (with sketches) practical field solution to compensate for the very compressible ground.
