31
In the Olmos irrigation tunnel project (Peru), what geological hazard caused cost overruns?
Discuss
Answer & Solution
Answer: Option C
Solution:
The tunnel experienced rock bursting due to high in-situ stress in andesite formations, damaging TBMs and delaying excavation.
32
Which type of landslide commonly affects road construction in the Nilgiris (India)?
Discuss
Answer & Solution
Answer: Option C
Solution:
Debris avalanches are frequent in the Nilgiris due to steep slopes, heavy rainfall, and weathered lateritic soil.
33
What was the key lesson from the Nicoll Highway collapse in Singapore (2004)?
Discuss
Answer & Solution
Answer: Option C
Solution:
The collapse was due to underestimated soil-structure interaction during diaphragm wall construction in soft clay conditions.
34
Which case study demonstrated successful river diversion for dam construction?
Discuss
Answer & Solution
Answer: Option D
Solution:
The Tehri Dam project required complex river diversion through twin tunnels due to challenging Himalayan terrain.
35
What engineering control was implemented in the Aizu Tunnel to manage gas emissions?
Discuss
Answer & Solution
Answer: Option A
Solution:
The tunnel passed through gas-bearing formations, so ventilation boreholes were installed to manage potentially explosive methane gases.
36
In which project did engineers face challenges due to high-pressure artesian groundwater during excavation?
Discuss
Answer & Solution
Answer: Option C
Solution:
Boston Big Dig encountered artesian groundwater conditions that complicated deep excavations. Engineers used advanced dewatering and waterproofing to mitigate this.
37
Which structure used a geological barrier to prevent radioactive waste leakage?
Discuss
Answer & Solution
Answer: Option A
Solution:
Yucca Mountain was selected for nuclear waste storage due to its volcanic tuff barrier that prevents groundwater movement and leakage.
38
What is the main geological concern in constructing underground metros in coastal cities?
Discuss
Answer & Solution
Answer: Option C
Solution:
Saline water ingress is a key issue in coastal tunneling, as seen in projects like Mumbai Metro and Chennai Metro. Proper sealing and concrete protection are essential.
39
The Vasco da Gama bridge construction required which method for dealing with soft clay deposits?
Discuss
Answer & Solution
Answer: Option B
Solution:
Deep mixing method was used to improve soft clay stability in the Tagus River area during bridge piling operations.
40
During the construction of Bhakra Dam, what geological feature was stabilized to ensure dam safety?
Discuss
Answer & Solution
Answer: Option A
Solution:
A shear zone was detected near the foundation and required grouting and drainage galleries to stabilize the foundation rocks.
