Correct option is D
·
Factors Affecting Embankment Settlement:
·
Void Ratio: A high void ratio means more void spaces in the soil, leading to greater settlement as the voids compress under load.
·
Density of Soil: Denser soils settle less compared to loose soils.
·
Water Viscosity Type: The viscosity of water affects the rate at which pore water is expelled from the soil during consolidation.
·
Comprehensive Influence:
· All these factors collectively determine the settlement characteristics of an embankment.
