Challenge Problems
Push your limits with advanced challenges
A construction site has a loading of 50 kN/m² applied on the surface. If the unit weight of the soil is 18 kN/m³ and the depth of interest is 4 m below the surface, calculate the effective stress at that depth when the pore water pressure is 10 kN/m².
💡 Hint: Use the formulas for total and effective stress!
Discuss how negative pore pressure could affect the effective stress in a partially saturated soil above the water table, especially in terms of capillary rise.
💡 Hint: Consider suction effects and water dynamics in soils!
