Section 4: Soil and Water Conservation Engineering

Soil Mechanics

Subtopic: Fundamental definitions and relationships

Question Statement:

For a fully saturated soil sample (degree of saturation $S = 100\%$), the relationship between void ratio $e$, moisture content $w$, and specific gravity of soil solids $G_s$ is:

Options:

  • (A) $e = w G_s$
  • (B) $e = w / G_s$
  • (C) $e = G_s / w$
  • (D) $e = w + G_s$

Answer Key:

A

Step-by-Step Solution & Explanation

General soil phase relationship: $e S = w G_s$. Since $S = 1.0$ at full saturation: $e = w G_s$.
