Each section contains 100 MCQs on Case Studies and Applied Geological Engineering Projects .
81
What was a key reason for slope instability during the Malin Landslide (Maharashtra, 2014)?
Discuss
Answer & Solution
Answer: Option C
Solution:
Heavy rainfall and deforestation were primary contributors to the Malin landslide. Excessive water infiltration reduced shear strength of the slope material, and tree removal eliminated root reinforcement, triggering slope failure.
82
What geological factor led to construction delay in the Atal Tunnel project?
Discuss
Answer & Solution
Answer: Option B
Solution:
The fault zone with water ingress in the Seri Nallah section led to excessive inflow of water and unstable tunneling conditions, causing delays and the need for additional support systems.
83
In the case of the Three Gorges Dam, what major geological concern was addressed during planning?
Discuss
Answer & Solution
Answer: Option B
Solution:
The Three Gorges Dam is in a seismically active region. Seismic risk assessment was crucial in the design of dam structures and slope stabilization along the reservoir.
84
Which Indian project required rock bolting and shotcrete to stabilize hill slopes near roadways?
Discuss
Answer & Solution
Answer: Option D
Solution:
The Char Dham Road Project passes through geologically weak Himalayan terrain. Rock bolting and shotcrete are employed extensively to stabilize rock cuttings and prevent landslides.
85
What monitoring method was used in the Sikkim Hydro Project to track tunnel deformation?
Discuss
Answer & Solution
Answer: Option C
Solution:
Convergence meters measure the inward movement of tunnel walls. They were used in the Sikkim Hydro Project to assess tunnel stability under high stress and fractured rock.
86
Which bridge had to consider foundation on weathered schist and required deep piling?
Discuss
Answer & Solution
Answer: Option A
Solution:
Vidyasagar Setu in Kolkata was built over soft soils and weathered schist layers. Deep piling ensured stability of the cable-stayed bridge despite challenging subsurface conditions.
87
What was a key cause of failure in the St. Francis Dam (1928)?
Discuss
Answer & Solution
Answer: Option C
Solution:
The failure occurred due to geological instability in schist and faulted rock. Water seepage weakened the foundation, and the dam collapsed catastrophically.
88
In the Banihal-Qazigund railway tunnel, what was the main hazard encountered?
Discuss
Answer & Solution
Answer: Option C
Solution:
The tunnel passed through the Himalayan geology with several fault zones. Water ingress in these fault zones posed continuous hazard during construction.
89
Which dam construction faced challenges due to uplift pressure beneath its base?
Discuss
Answer & Solution
Answer: Option B
Solution:
Bhakra Dam had to address uplift pressure from groundwater beneath the dam base. Drainage galleries and pressure relief wells were constructed to mitigate this issue.
90
The primary reason for tunnel collapse in Hallands�s Tunnel (Sweden) was:
Discuss
Answer & Solution
Answer: Option B
Solution:
The Hallands�s Tunnel experienced water inflow due to inadequate waterproofing in fractured rock. Additional sealing techniques had to be implemented mid-project.
