41
Which project demonstrated successful use of tunnel boring machines in fractured rock conditions?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Pir Panjal Tunnel (India) used TBMs in complex Himalayan terrain with fractured rock and water ingress, managed with shotcrete and steel ribs.
42
In the La Conchita landslide (USA), what was the dominant triggering factor?
Discuss
Answer & Solution
Answer: Option B
Solution:
The landslide was triggered by heavy rainfall, saturating the colluvium and initiating slope failure, illustrating the role of hydrology in slope stability.
43
What major challenge was encountered in the El Teniente Mine tunnel project in Chile?
Discuss
Answer & Solution
Answer: Option C
Solution:
Rock bursts occurred due to high stress in the Andes Mountains, leading to costly repairs and support enhancements in the tunnel system.
44
Which Indian dam faced controversy due to resettlement and geological risks?
Discuss
Answer & Solution
Answer: Option B
Solution:
The Sardar Sarovar Dam faced both social resettlement challenges and concerns about seismic risks and foundation integrity in the basaltic Deccan Traps.
45
What mitigation method was implemented at the Vajont Dam post-failure?
Discuss
Answer & Solution
Answer: Option A
Solution:
After the deadly landslide in 1963, authorities lowered the reservoir level permanently to reduce hydrostatic pressure and risk of future slope failure.
46
Which factor contributed most to the failure of the Highland Towers (Malaysia)?
Discuss
Answer & Solution
Answer: Option B
Solution:
Excavation at the toe of the slope for a retaining wall during rainfall led to slope failure, ultimately causing the collapse of the Highland Towers.
47
In the Metro Tunnel Project of Melbourne, what tool was used to monitor ground movement?
Discuss
Answer & Solution
Answer: Option A
Solution:
Tiltmeters were installed to measure small angular deformations in adjacent buildings, helping to assess real-time ground movement during tunneling.
48
What lesson was learned from the Vajont disaster regarding geological surveys?
Discuss
Answer & Solution
Answer: Option C
Solution:
The disaster showed that rock mass behavior and slope geology must be thoroughly investigated; the failure occurred due to a massive rockslide into the reservoir, not dam failure.
49
What kind of foundation was used for the Millau Viaduct in France?
Discuss
Answer & Solution
Answer: Option D
Solution:
The Millau Viaduct used deep pile foundations embedded into limestone bedrock, designed to resist wind loads and dynamic stresses.
50
What key monitoring system was used in the Hong Kong-Zhuhai-Macau Bridge project?
Discuss
Answer & Solution
Answer: Option C
Solution:
Fiber optic sensors were embedded in structural components to monitor strain, temperature, and displacement in real time, improving safety and maintenance.
