In the Panama Canal Expansion, what was a key geological issue during excavation?
A. Lava flow intrusion
B. Swelling clay
C. Fault movement
D. Volcanic ash
Answer: Option B
Solution (By Examveda Team)
Swelling clay (specifically montmorillonite) caused slope instability. When exposed to water, this clay expanded, exerting pressure on retaining structures and increasing excavation risks.Which geotechnical failure occurred in the 1963 Vajont Dam disaster in Italy?
