FAQs on Rankine's Formula Video Lecture - Civil Engineering Optional Notes for UPSC

1. What is Rankine's Formula in civil engineering?
Ans. Rankine's Formula is a stress calculation formula that is used in civil engineering to determine the lateral earth pressure acting on retaining walls. It takes into account the soil properties, wall geometry, and other factors to calculate the maximum lateral pressure that the soil exerts on the wall.
2. How is Rankine's Formula different from Coulomb's Theory?
Ans. Rankine's Formula considers both the active and passive earth pressures acting on a retaining wall, while Coulomb's Theory only considers the active pressure. Rankine's Formula provides a more comprehensive analysis of the soil-wall interaction, taking into account both the soil properties and the wall geometry.
3. When is Rankine's Formula used in civil engineering projects?
Ans. Rankine's Formula is commonly used in the design and analysis of retaining walls, basement walls, sheet pile walls, and other structures that are subjected to lateral earth pressure. It helps engineers determine the stability and safety of these structures under different soil conditions.
4. What are the limitations of Rankine's Formula?
Ans. Rankine's Formula makes several assumptions about the soil behavior and wall geometry, which may not always hold true in practical applications. It does not account for factors such as soil cohesion, wall roughness, groundwater effects, and construction sequence, which can affect the actual lateral pressure acting on the wall.
5. How can Rankine's Formula be applied in real-life civil engineering projects?
Ans. Engineers can use Rankine's Formula to calculate the lateral earth pressure acting on a retaining wall and design the wall to withstand these pressures. By considering the soil properties, wall geometry, and other relevant factors, engineers can ensure the stability and safety of the structure in different soil conditions.
