Course Learning Objectives:
The objective of this course is:
To introduce the course: Engineering Geology to the Civil Engineering graduates.
To enable the students, understand what minerals and rocks are and their formation and
identification.
To highlight significance/ importance/ role of Engineering Geology in construction of Civil
Engineering structures.
To enable the student, realise its importance and applications of Engineering Geology in Civil
Engineering constructions.
Course Outcomes:
Upon the successful completion of this course, the students will be able to:
Identify and classify the geological minerals
Measure the rock strengths of various rocks
Classify and measure the earthquake prone areas to practice the hazard zonation
Classify, monitor and measure the Landslides and subsidence
Prepares, analyses and interpret the Engineering Geologic maps
Analyses the ground conditions through geophysical surveys.
Test the geological material and ground to check the suitability of civil engineering project
construction.
