TOTAL: 45 PERIODS + 15 TUTORIALS
OUTCOMES:
Upon completion of this course, the students will able to
 Classify the soil based on the index properties of soil.
 Get familiarized with the soil characteristics due to the presence of water in soil.
 Estimate the stress distribution in soil and also know its behavior under compression.
 Estimate the shear strength parameters of soil using different laboratory tests.
 Analyze the slope stability using different methods and will also know the different slope protection
measures.
