In the Sikkim Himalayas, what geological constraint affects road construction?
A. Strong igneous rocks
B. Thick laterite cover
C. Unstable slopes and landslides
D. Flat terrain
Answer: Option C
Solution (By Examveda Team)
The Sikkim Himalayas are prone to landslides and slope instability, particularly during monsoon seasons. Geotechnical engineering solutions are critical in such terrains for road stability.Which geotechnical failure occurred in the 1963 Vajont Dam disaster in Italy?
