Question 1

What is the primary purpose of the Consolidated-Drained test?

  • To determine shear strength parameters
  • To measure soil moisture
  • To assess soil color

💡 Hint: Think about the properties engineers need for design.

Question 2

True or False: The Mohr-Coulomb failure envelope only applies to saturated soils.

  • True
  • False

💡 Hint: Consider other soil conditions outside saturation.

Challenge Problems

Push your limits with challenges.

Question 1

A soil sample yields a cohesion of 5 kPa and an angle of internal friction of 30 degrees during a CD test. Calculate the shear strength of the soil when the normal stress is 20 kPa.

💡 Hint: Remember to convert the angle from degrees to use in the tangent function.

Question 2

An engineer needs to design a wall in clay known to have a failure envelope of c = 8 kPa and φ = 25 degrees. What factors should the engineer consider if the wall is to be built below groundwater level?

💡 Hint: Think about what happens to pressures when water is present.
