61
What was a major success in the Jubail Industrial City foundation project in Saudi Arabia?
Discuss
Answer & Solution
Answer: Option B
Solution:
Engineers dealt with saline soils by mixing with pozzolanic materials and using deep foundations, enabling stable structures in a harsh marine desert.
62
What was the innovative slope stabilization technique used in the Nilgiri Hills road widening?
Discuss
Answer & Solution
Answer: Option C
Solution:
Soil nailing combined with bioengineering was implemented to stabilize the slopes while promoting vegetation regrowth in the ecologically sensitive Nilgiri region.
63
In the Bujagali Hydropower Project (Uganda), geological surveys focused on which key aspect?
Discuss
Answer & Solution
Answer: Option B
Solution:
Extensive studies found fractures in the granite foundation, which were treated with grouting before dam construction to prevent seepage and ensure integrity.
64
Which metro project used cross passages for safety in twin tunnel alignment?
Discuss
Answer & Solution
Answer: Option B
Solution:
Chennai Metro implemented cross passages every 250-300 meters to enhance safety and facilitate evacuation in case of emergency.
65
The Niagara Tunnel Project encountered which geological hazard?
Discuss
Answer & Solution
Answer: Option D
Solution:
Engineers faced karst features (cavities in limestone) which posed water ingress risks. These were sealed using pre-injection grouting and real-time monitoring.
66
What type of rock caused excessive wear on TBM cutters in the Delhi Metro Phase III tunneling?
Discuss
Answer & Solution
Answer: Option B
Solution:
Quartzite is a very hard, abrasive metamorphic rock. In Delhi Metro Phase III, TBMs experienced high tool wear when tunneling through quartzite layers, requiring frequent maintenance and cutter replacements.
67
In the Panama Canal Expansion, what was a key geological issue during excavation?
Discuss
Answer & Solution
Answer: Option B
Solution:
Swelling clay (specifically montmorillonite) caused slope instability. When exposed to water, this clay expanded, exerting pressure on retaining structures and increasing excavation risks.
68
Which major bridge project required subsurface profiling due to liquefiable soil layers?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Bandra-Worli Sea Link was constructed on reclaimed coastal soils. Extensive geotechnical investigations found liquefiable layers, and deep pile foundations were adopted to mitigate seismic risks.
69
The main geological concern in the construction of the Gotthard Base Tunnel was:
Discuss
Answer & Solution
Answer: Option C
Solution:
The Gotthard Base Tunnel passed through several faulted zones with fractured and water-bearing rocks. These required real-time monitoring, reinforced linings, and drainage systems.
70
Which dam faced challenges due to sediment inflow from rapidly eroding catchment?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Aswan High Dam on the Nile River experienced significant sediment accumulation in its reservoir (Lake Nasser), reducing storage capacity and posing long-term operational challenges.
