A soil sample 10 mm thick in an oedometer with one-way drainage was subjected to an increase in pressure of 150 kPa. Use the graph below to predict the excess pore pressure at a point 5.5 mm from the drainage end, after 40 minutes, when Tv is calculated to be 0.35.

During soil consolidation process, when t > 0, how do soil effective stress,pore pressure and soil volume change?

What do you call a sudden increase in pore pressure due to applied loading conditions?

Oedometer A is manual with porous stones at top and bottom and has a sample 16 mm thick. Oedometer B is hydraulic with drainage at the bottom only and has a sample 8 mm thick. The maximum drainage path, H, for A and B, respectively, will be:Group of answer choices8 mm and 8 mm16 mm and 4 mm16 mm and 8 mm8 mm and 4 mm

The soil will have the greatest drainage if it has:Very smooth textureA low temperatureSmall particlesBig particles

The vertical total stress in an element of soil at a depth of 5m within a clay embankment has been estimated to be 139 kPa. The porewater table has been found to be 1.1 m above the element. Estimate the horizontal shear strength in kPa in the element (take the effective cohesion to be 15.2 kPa, the effective friction angle to be 30.3o and the unit weight of water to be 10 kN/m3).(give your answer to 1 d.p.)
