31
In the Vajont Dam disaster (Italy, 1963), the catastrophic wave was caused by:
Discuss
Answer & Solution
Answer: Option C
Solution:
The Vajont disaster was triggered by a massive landslide into the reservoir, causing a wave to overtop the dam. The dam itself remained intact, but the landslide displaced water with deadly force.
32
The Gotthard Base Tunnel in Switzerland is notable for:
Discuss
Answer & Solution
Answer: Option B
Solution:
The Gotthard Base Tunnel is the deepest and longest railway tunnel through the Alps, involving complex rock mechanics and geological mapping.
33
What method was primarily used to stabilize tunnel portals in the Konkan Railway project?
Discuss
Answer & Solution
Answer: Option B
Solution:
In the Konkan Railway project, many tunnel portals were stabilized using rock bolting and shotcrete to deal with weak lateritic soils and rainfall-induced instability.
34
The Panama Canal expansion required geological attention due to:
Discuss
Answer & Solution
Answer: Option C
Solution:
Karst formations and associated sinkholes posed risks in the Panama Canal expansion, requiring detailed subsurface investigation.
35
In the Three Gorges Dam project (China), what was a key geological risk?
Discuss
Answer & Solution
Answer: Option C
Solution:
The dam's construction altered stress regimes, triggering induced seismicity and landslides. Geological assessments were vital for risk mitigation.
36
In the Delhi Metro project, what was the main geotechnical challenge in Old Delhi?
Discuss
Answer & Solution
Answer: Option B
Solution:
Tunneling beneath Old Delhi involved dealing with loose alluvial soils and a high groundwater table, necessitating closed-face TBMs.
37
The cause of the St. Francis Dam disaster in California (1928) was:
Discuss
Answer & Solution
Answer: Option A
Solution:
The dam failed due to a geological misinterpretation of weak schist and faulted conglomerate in the foundation, causing a massive collapse.
38
The subsidence in the Mexico City Metropolitan area is mostly due to:
Discuss
Answer & Solution
Answer: Option B
Solution:
Over-extraction of groundwater from soft lacustrine clay has caused widespread land subsidence in Mexico City.
39
In the Koyna Dam case, the 1967 earthquake was attributed to:
Discuss
Answer & Solution
Answer: Option B
Solution:
The Koyna earthquake is a classic example of reservoir-induced seismicity, where the impounding of water triggered movement along existing faults.
40
During the Alaskan pipeline project, which geotechnical issue required special design?
Discuss
Answer & Solution
Answer: Option B
Solution:
The pipeline crosses permafrost zones, requiring elevated and insulated sections to prevent thawing and instability.
