Following Civil Engineering Multiple choice objective type questions and answers will help you in practicing this topic for GATE related to soil mechanics.The MCQs in the soil mechanics part comprises from the following topics-
Sub-surface investigations-scope, drilling bore holes, sampling, penetration tests, plate load test. Earth pressure theories, effect of water table, layered soils. Stability of slopes-infinite slopes, finite slopes. Foundation types-foundation design requirements. Shallow foundations-bearing capacity, effect of shape, water table and other factors, stress distribution, settlement analysis in sands and clays. Deep foundation – pile types, dynamic and static formulas, load capacity of piles in sands and clays, negative skin friction.

1 ) As per the recent classification of Indian Standard Classification system , a sample of silty clay with liquid limit of 40% and plasticity index of 28% is classified as
2 ) A fine-grained soil has a liquid limit of 300% and a plastic limit of 55%. The natural water content of the soil in the field is 80% and the clay content is 60%.
- Determine the plasticity index, the liquidity index and the activity.
- Describe the soil state in the field
- If this soil were under a concrete slab used as a foundation for a building and water were to seep into it from watering of a lawn, what would you expect to happen to the foundation?
3 ) Which of the following types of soil is transported by gravitational forces
- dune sand.
4 ) A fully saturated soil is said to be
- one phase system
- two phase system with soil and air
- two phase system with soil and water
- three phase system.
