Challenge Problems
Push your limits with challenges.
Question 1
Consider a soil sample that shows a cohesion value of 15 kPa and an internal friction angle of 25°. How would you expect this soil to perform in terms of stability under loading? Discuss.
💡 Hint: What happens to soil when subjected to stress relative to its strength?
Question 2
In a Direct Shear Test, a soil sample fails at a normal stress of 200 kPa with a maximum shear stress of 100 kPa. Calculate the effective cohesion and friction angle, given the water table has significant effects.
💡 Hint: Remember to factor in any pore water pressure impacts.
