GEOTECHNICAL ENGINEERING – I
Course Studying Goals:
The target of this course is:
• To allow the coed to search out out the index properties of the soil and classify it.
• To impart the idea of seepage of water by way of soils and decide the
• To allow the scholars to distinguish between compaction and consolidation of
soils and to find out the magnitude and the speed of consolidation settlement.
• To allow the coed to know the idea of shear power of soils,
evaluation of the shear parameters of sands and clays and the areas of their
Upon the profitable completion of this course
• The coed should know the definition of the assorted parameters associated to soil
mechanics and set up their inter-relationships.
• The coed ought to be capable to know the strategies of dedication of the assorted
index properties of the soils and classify the soils.
• The coed ought to be capable to know the significance of the completely different engineering
properties of the soil similar to compaction, permeability, consolidation and shear
power and decide them within the laboratory.
• The coed ought to be capable to apply the above ideas in day-to-day civil
