Each section contains 100 MCQs on Case Studies and Applied Geological Engineering Projects .
11
Which parameter was critical in designing foundations for the Petronas Towers in Kuala Lumpur?
Discuss
Answer & Solution
Answer: Option A
Solution:
The depth to competent limestone bedrock was a key consideration for foundation design. Large-diameter bored piles were used to transfer loads through soft upper layers.
12
In the Bhuj Earthquake (2001), why did many buildings fail despite being away from the epicenter?
Discuss
Answer & Solution
Answer: Option A
Solution:
Soil liquefaction in the region caused ground instability. Structures built on loose sands and reclaimed land suffered severe damage due to loss of bearing capacity.
13
Which geological technique was used in tunneling for Metro Rail projects in Delhi?
Discuss
Answer & Solution
Answer: Option B
Solution:
The slurry shield TBM was used to handle soft soils and high groundwater pressure in Delhi Metro construction. This method prevents face collapse and reduces surface settlement.
14
What factor caused the failure of the St. Francis Dam (California, 1928)?
Discuss
Answer & Solution
Answer: Option A
Solution:
The St. Francis Dam failed due to lack of understanding of the geological conditions, particularly weak schist and faulted rock under the dam. It highlighted the importance of geological surveys in dam safety.
15
In the Sikkim Himalayas, what geological constraint affects road construction?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Sikkim Himalayas are prone to landslides and slope instability, particularly during monsoon seasons. Geotechnical engineering solutions are critical in such terrains for road stability.
16
What major geological factor delayed the construction of the Boston Big Dig project?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Boston Big Dig encountered significant delays due to soft clay and high groundwater levels. Extensive dewatering, ground improvement, and monitoring systems were implemented to control settlements.
17
Which stabilization technique was used in the case study of the unstable Nilgiris slopes in India?
Discuss
Answer & Solution
Answer: Option B
Solution:
Bio-engineering techniques, like using vegetation and vetiver grass, were employed to stabilize Nilgiri hill slopes. This method helps control erosion and improves slope stability sustainably.
18
In the case of the Tehri Dam in India, which seismic consideration was most critical?
Discuss
Answer & Solution
Answer: Option C
Solution:
Peak Ground Acceleration (PGA) was critical in seismic analysis for the Tehri Dam. The dam was located in a seismically active zone, and PGA values influenced the design of spillways and slopes.
19
What was the main cause of tunnel face collapse in the Heathrow Express Rail Link project?
Discuss
Answer & Solution
Answer: Option C
Solution:
The collapse occurred due to unsupported excavation in London clay, leading to loss of face stability. It emphasized the importance of real-time monitoring and pre-support measures.
20
In the Kaliasaur landslide case in Uttarakhand, which geological structure played a key role in slope failure?
Discuss
Answer & Solution
Answer: Option B
Solution:
The bedding planes dipping outward towards the valley facilitated downslope movement during rainfall, contributing to recurrent landslides.
