List of top Geotechnical Engineering Questions on Soil Mechanics asked in GATE CE

Consider a soil sample where the following parameters are defined:

  • \(S\) = Soil suction head
  • \(K\) = Hydraulic conductivity
  • \(w\) = Moisture content

If the moisture content (\(w\)) of the soil increases, which of the following statements regarding the soil suction head (\(S\)) and hydraulic conductivity (\(K\)) is correct?

A clay deposit is found to have a natural water content and void ratio that corresponds to a pre-consolidation pressure (\(\sigma'_{p}\)) that is greater than the present effective overburden pressure (\(\sigma'_{o}\)). This clay is best classified as:
For a two-lane, two-way highway, the length of a summit curve is ideally designed based on which parameter to ensure full operational efficiency (overtaking opportunities)?
