21
Why did the Malin landslide in Maharashtra (2014) cause severe damage?
Discuss
Answer & Solution
Answer: Option C
Solution:
The Malin landslide was caused by heavy rainfall combined with slope modification for agriculture. These anthropogenic activities reduced slope stability.
22
What was the major challenge in constructing Metro tunnels beneath heritage structures in Kolkata?
Discuss
Answer & Solution
Answer: Option B
Solution:
Vibration control was essential to protect Kolkata�s heritage structures. Special TBMs and real-time monitoring systems were used to minimize ground movements.
23
The 1964 Niigata Earthquake case is an example of which geotechnical failure?
Discuss
Answer & Solution
Answer: Option B
Solution:
The Niigata earthquake is a classic example of liquefaction, where saturated sandy soils lost strength, leading to tilting and collapse of buildings.
24
Which mitigation strategy was used in the Rio de Janeiro favela landslide-prone areas?
Discuss
Answer & Solution
Answer: Option C
Solution:
The main approach was improving drainage and planting vegetation to reduce pore pressure and erosion in unstable slopes of favelas.
25
What type of rock mass classification was applied in the construction of the El Teniente mine tunnels in Chile?
Discuss
Answer & Solution
Answer: Option A
Solution:
The Rock Mass Rating (RMR) system was used for tunnel support design in El Teniente mine. It evaluates rock quality based on strength, joint spacing, groundwater, and other parameters.
26
In the case of the Metro tunnel beneath the Hooghly River, which technique was used to avoid water ingress?
Discuss
Answer & Solution
Answer: Option C
Solution:
A slurry shield Tunnel Boring Machine was used under the Hooghly River to balance water pressure and prevent ingress.
27
What type of hazard is associated with abandoned quarries in urban areas?
Discuss
Answer & Solution
Answer: Option B
Solution:
Abandoned quarries often pose slope stability and water pollution hazards. These areas can collect rainwater and cause contamination if not managed properly.
28
Which solution was applied in the stabilization of permafrost foundations in Alaska�s Trans-Alaska Pipeline?
Discuss
Answer & Solution
Answer: Option A
Solution:
Soil refrigeration or thermosyphons were installed to keep permafrost frozen and stable, preventing settlement of the Trans-Alaska Pipeline.
29
In the construction of hydropower projects in the Himalayas, which geological hazard is most common?
Discuss
Answer & Solution
Answer: Option C
Solution:
Landslides are a frequent hazard in Himalayan hydro projects due to steep terrain and monsoonal rains, requiring robust slope protection.
30
What failure mechanism caused the collapse of the Teton Dam (USA, 1976)?
Discuss
Answer & Solution
Answer: Option B
Solution:
The Teton Dam failed due to internal erosion (piping) through vulnerable soil in the dam�s right abutment. This is a key lesson in seepage control and foundation assessment.
