Pressure (kN/m2) Void Ratio after the test 400 0.96 800 0.78 The initial thickness of the tested sample was 19.6 mm with a moisture content of 18%. The sample takes 8 minutes to achieve 25% of consolidation. 1. Estimate the total consolidation settlement of the clay layer based on the variation of the pressure as given in Table 2. Estimate the time to achieve 50% and 90% degree of consolidation and suggest ONE (1) method to accelerate the consolidation process of the above clay layer. Use sketches to support your answers.

A conventional drained triaxial compression test was conducted on a normally consolidated clay sample under an effective confining pressure of 200 kPa. The deviator stress at failure was found to be 400 kPa. An identical specimen of the same terclay sample is isotropically consolidated to a confining pressure of 200 kPa and subjected to standard undrained triaxial compression test. If er the deviator stress at failure is 150 kPa, the pore pressure developed (in kPa, upto one decimal place) is
