the stress at particles contact

a physical parameter that can be measured

important because it is a function of engineering properties of soil

all of the above

equal increase in pore water pressure and total stress

equal decrease in pore water pressure and total stress

increase in pore water pressure but decrease in total stress

decrease in pore water pressure but increase in total stress

zero and zero

0.5 kg/cm2 and zero

0.5 kg/cm2 and 0.5 kg/cm2

1.0 kg/cm2 and 0.5 kg/cm2

effective stress is reduced due to decrease in total stress only but pore water pressure does not change

effective stress is reduced due to increase in pore water pressure only but total stress does not change

total stress is reduced due to increase in pore water pressure only but effec-tive stress does not change

total stress is increased due to de-crease in pore water pressure but effective stress does not change

flow condition occurring in cohesive soils

flow condition occurring in cohesionless soils

flow condition occurring in both cohesive and cohesionless soils
