Question

Match List-I (Situation) with List-II (Stress Path) and select the correct answer using the codes given below the lists:
List-I
A. Embankment construction
B. Excavation of a pit
C. Hydrostatic loading
D. Lateral expansion of a backfill
List-II
1. Stress path moves in left side upward direction
2. Stress path moves in left side downward direction
3. Stress path moves in right side upward direction
4. Stress path moves along the horizontal axis

• A. A - 3 , B - 2 , C - 1, D - 4
• B. A - 3 , B - 2 , C - 4, D - 1
• C. A - 2 , B - 3 , C - 4, D - 1
• D. A - 2 , B - 3 , C - 1, D - 4

Answer 1

The correct option is B A - 3 , B - 2 , C - 4, D - 1

In hydrostatic loading $\Delta {\sigma }_h=\Delta {\sigma }_v$ So stress path moves along a horizontal axis. Lateral expansion of backfill means $\Delta {\sigma }_h<0$ and $\Delta {\sigma }_v=0$ so stress path moves in left side upward direction. During embankment constructiont $\Delta {\sigma }_h=0$ and $\Delta {\sigma }_v>0$ so stress path moves in right side upward direction. During excavation of a pit $\Delta {\sigma }_h=0$ and $\Delta {\sigma }_v<0$ so stress path moves in left side downward direction.
