Please determine if the following statement is true or false, and explains why.

1. Effective stress is defined as total stress minus pore pressure.

2. For a given consolidation stress, a normally consolidated clay will be stronger than an overconsolidated clay.

Expert Solution

1. True

Total stress is due to self wight if soil(wieght of solid + weight of water) or due to applied overburden pressure.

Pore water pressure = is the pressure which is being transmitted by pore fluid and is which is equal to qeight of fluid.

Effective stress = it is stres which is being transfered in soil mass by grains to grains which tends to force the particles to come into close state of contact.

Hence we can say Effective stress = total stress - pore water pressure

Hence effective stress = total stress - pore water pressure

2. false

Because Normally consolidated soil is going to deform under a certain pressure but over consolidated soil is already deformed under that pressure if that is preconsolidation pressure.

Hence Normally consolidated soil is weaker than over consolidated soil.
