51
The primary failure cause in the St. Francis Dam disaster (1928) was related to:
Discuss
Answer & Solution
Answer: Option C
Solution:
The St. Francis Dam failed due to unrecognized weak sedimentary rock at the foundation. The left abutment was composed of schist that weakened when saturated, leading to collapse.
52
Which project successfully employed geotextiles in slope stabilization?
Discuss
Answer & Solution
Answer: Option B
Solution:
Hong Kong Airport Extension used geotextiles in embankment construction to improve slope stability and reduce settlement over reclaimed land.
53
Which Indian tunnel project tackled Himalayan squeeze effectively using rock bolts and shotcrete?
Discuss
Answer & Solution
Answer: Option A
Solution:
The Atal Tunnel in Himachal Pradesh faced high overburden pressure in weak Himalayan rocks, countered with rock bolts, lattice girders, and shotcrete.
54
What geological risk was most significant in the Karakoram Highway construction?
Discuss
Answer & Solution
Answer: Option C
Solution:
Glacial lake outburst floods (GLOFs) posed major risks in the region, damaging the Karakoram Highway multiple times due to rapid water and debris flows.
55
In the Gotthard Base Tunnel, what key monitoring was used to assess excavation safety?
Discuss
Answer & Solution
Answer: Option C
Solution:
Tunnel convergence monitoring (using extensometers and lasers) helped engineers track tunnel deformation under stress, ensuring safety in deep Alpine rocks.
56
The main geological concern during the construction of the Hoover Dam was:
Discuss
Answer & Solution
Answer: Option C
Solution:
Engineers were concerned about the competency of foundation rock (limestone and sandstone). They performed extensive grouting to strengthen it.
57
Which project required rerouting due to discovery of fault zones?
Discuss
Answer & Solution
Answer: Option D
Solution:
The Crossrail Project in London had to reroute segments when active fault zones and complex urban geology were encountered.
58
Which dam project used a digital twin for real-time stress simulation?
Discuss
Answer & Solution
Answer: Option A
Solution:
Tehri Dam in India incorporated a digital twin model during recent upgrades, enabling engineers to simulate stress and reservoir load impacts in real time.
59
In which project was basalt rock tunneling a significant challenge?
Discuss
Answer & Solution
Answer: Option A
Solution:
Mumbai Metro Line 3 had to tunnel through Deccan Trap basalt, which is hard and abrasive, requiring specialized TBM cutters and cooling systems.
60
Which landslide project demonstrated the use of remote sensing for hazard mapping?
Discuss
Answer & Solution
Answer: Option D
Solution:
Oso Landslide studies used LiDAR and InSAR remote sensing to reconstruct slope failure and map landslide-prone zones.
