11. In the Seattle Alaskan Way Tunnel, why was tunneling halted temporarily? A. Labor strike B. TBM hit unexpected boulder C. Groundwater flooding D. TBM encountered a steel pipe Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option D Solution: Tunneling stopped when the TBM (Bertha) hit a steel pipe left from a previous investigation, damaging the cutter head and requiring major repairs.
12. What was the cause of ground settlement during MRT construction in Bangkok? A. Water table rise B. Organic soft clay compression C. Lava flows D. Glacial tills Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option B Solution: The region's subsoil contains organic soft clay with high compressibility, leading to settlement when subjected to construction loads.
13. In the Itaipu Dam, what ensured stability of the rock foundation? A. Preloading B. Jet grouting C. Extensive geological mapping and grouting D. Soil nails Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: Engineers conducted detailed geological mapping and grouting to improve the foundation rock mass of this massive hydroelectric project.
14. The main engineering solution for the Rotterdam Maasvlakte port extension was: A. Offshore wind turbines B. Floating piers C. Sand nourishment and dike reinforcement D. Subsea tunnels Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: Engineers used sand nourishment and reinforced dikes to manage coastal erosion and land reclamation for port expansion.
15. Which type of fault posed a risk to the Taipei 101 Tower construction? A. Normal fault B. Thrust fault C. Strike-slip fault D. Blind fault Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option D Solution: A blind fault (not visible at the surface) near the site posed a seismic risk, requiring specialized design for earthquake resilience.
16. Which geotechnical instrument is used in most case studies to monitor slope stability? A. Anemometer B. Strain gauge C. Inclinometer D. Thermistor Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: An inclinometer measures horizontal ground movement, making it vital for slope stability monitoring in landslide-prone areas.
17. In the La Conchita landslide, what prior geological evidence existed? A. Fault scarp B. Ancient slide deposits C. Coral reef exposure D. Sinkholes Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option B Solution: Before the 2005 landslide, ancient landslide deposits were mapped in the same area, suggesting high risk that had been overlooked.
18. Why was a tunnel chosen over a bridge in the Stockholm Bypass project? A. Lower cost B. Shorter route C. Geological stability and aesthetics D. Traffic constraints Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: Due to dense urbanization and geological considerations, a tunnel provided better long-term stability and preserved the natural landscape.
19. What geological hazard complicated the construction of the Tapovan-Vishnugad hydro project? A. Earthquake B. Avalanche C. Glacial lake outburst flood (GLOF) D. Volcanic eruption Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: A GLOF (Glacial Lake Outburst Flood) struck the region, damaging the dam infrastructure and raising alarms about Himalayan glacial risks.
20. Which advanced technique helped map sinkholes in Florida? A. Seismic tomography B. Satellite radar interferometry (InSAR) C. Ground Penetrating Radar D. Resistivity tomography Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option B Solution: InSAR allowed detection of 1 2 3 4 5 6 7 8 9 10 Read More Section(Case Studies and Applied Geological Engineering Projects) Each Section contains maximum 100 MCQs question on Case Studies and Applied Geological Engineering Projects.
