Challenge Problems
Push your limits with advanced challenges
A geotechnical engineer conducts a triaxial test on a soil sample that shows a cohesion of 15 kPa and a friction angle of 25°. Calculate the shear strength when the normal stress is 80 kPa.
💡 Hint: Work through the equation step-by-step.
A construction site on sandy soil has been found inadequate for supporting a foundation based on Mohr-Coulomb failure criteria. Discuss what soil properties might be problematic and suggest solutions.
💡 Hint: Consider how different types of soil interact under pressure.
