Given a soil sample's initial void ratio is 0.8, with an effective stress of 50kPa. If the sample undergoes virgin compression to an effective stress of 90kPa, calculate the new void ratio assuming a linear relationship.
💡 Hint: You will need to determine the change based on effective stress increases.
Discuss how knowledge of hysteresis in soil can influence the design of a foundation for a high-rise building.
💡 Hint: Consider safety and stability in engineering design.
