AKTU Geotechnical Engineering Lab (BCE552) Syllabus PDF – B.Tech 3rd Year

Course Outcomes: After completion of the course student will be able to:

CO1. Calculate and explain the water content and specific gravity of soil.

CO2. Measure and analyze the in-situ density and relative density of soil.

CO3. Analyze and evaluate the grain size distribution and consistency limits of soil.

CO4. Determine and evaluate the dry density of soil through compaction processes and assess the permeability of soil.

CO5. Perform and evaluate shear strength tests (direct shear and triaxial) to assess soil stability under various conditions.

PART -A (To be performed in lab)

1. Determination of water content of a given moist soil sample by (i) oven drying method, (ii) pycnometer method.
2. Determination of specific gravity of a given soil sample by (i) density bottle, (ii) pycnometer method.
3. Determination of in situ dry density of soil mass by (i) core-cutter method, (ii) sand replacement method.
4. Determination of relative density of a given soil sample.
5. Determination of complete grain size distribution of a given soil sample by sieve analysis and sedimentation (hydrometer) analysis.
6. Determination of consistency limits (liquid, plastic and shrinkage limits) of the soil sample used in experiment no. 5 (grain-size analysis).
7. Determination of shear strength of soil by Direct shear test.
8. Determination of compaction characteristics (OMC & MDD) of a given soil sample.
9. Determination of permeability of a remoulded soil sample by constant head &/or falling head method.
10. Determination of consolidation characteristics of a remoulded soil sample by an odometer test.
11. Determination of shear strength characteristics of a given soil sample by U/U test from Triaxial Compression Machine.
12. Retrieving soil samples and conducting SPT tests by advancing boreholes through hand-held auger. Note: Any 8 experiments are to be performed from the list of experiments. PART-B It is mandatory to perform experiments using virtual lab wherever applicable.
