Question

Choose the correct option from the following in relation to occurrence of liquefaction of soil:

• A. High ground water table, static load and loose fine sand
• B. High ground water table, static load and dense coarse sand
• C. High ground water table, dynamic load and loose fine sand
• D. High ground water table, dynamic load and dense coarse sand

Hint:

Liquefaction risk: high water table + dynamic load + loose fine sand; avoid such conditions in construction.

Answer 1

The Correct Option is C

Liquefaction of soil occurs under conditions of a high ground water table, dynamic load, and loose fine sand: - A high water table saturates the soil, reducing its strength. - Dynamic loads (e.g., earthquakes) increase pore pressure, causing loose fine sand to lose cohesion and behave like a liquid.
