18CVL77 Geotechnical Engineering Laboratory syllabus for CV



A d v e r t i s e m e n t

Module-1 GEOTECHNICAL ENGINEERING LABORATORY 0 hours

Course Learning Objectives:

This course will enable students to;

1. To carry out laboratory tests and to identify soil as per IS codal procedures

2. To perform laboratory tests to determine index properties of soil

3. To perform tests to determine shear strength and consolidation characteristics of soils

Modules

1. Field identification of soil, Specific gravity test (pycnometer and density bottle method).Water content determination by oven drying and Pycnometer method, rapid moisture meter method.

 

2. Grain size analysis

i. Sieve analysis

ii. Hydro meter analysis

 

3. In-situ density tests

i. Core-cutter method

ii. Sand replacement method

 

4. Consistency limits

i. Liquid limit test(by Casagrande's and cone penetration method)

ii. Plastic limit test iii. Shrinkage limit test

 

5. Standard compaction test (light and heavy compaction)

 

6. Co-efficient of permeability test

i. Constant head test

ii. Variable head test

 

7. Shear strength tests

i. Unconfined compression test

ii. Direct shear test

iii. Triaxial test (unconsolidated undrained test only)

 

8. Consolidation test :To determine pre consolidation pressure only(half an hour per loading-test).

 

9. Laboratory vane shear test

 

10. Demonstration of Swell pressure test, Standard penetration test and boring equipment

 

Course outcomes:

Students will be able to conduct appropriate laboratory/field experiments and interpret the results to determine

1. Physical and index properties of the soil

2. Classify based on index properties and field identification

3. To determine OMC and MDD, plan and assess field compaction program

4. Shearstrengthandconsolidationparameterstoassessstrengthanddeformationcharacteristics

5. In-situshear strength characteristics(SPT-Demonstration)

 

Question paper pattern:

  • All experiments are to be included in the examination except demonstration exercises.
  • Candidate to perform experiment assigned to him.
  • Marks are to be allotted as per the split up of marks shown on the cover page of answer script.
