Engineering Geology is the application of the geological sciences to Civil Engineering practice for the purpose of recognizing the location, design, construction, operation and maintenance of engineering projects such as Dams, Barrages, Bridges, High rise buildings and other such important projects. Students will be able to know the details of rock formation and study of rock cycle. Students will be able to identify different minerals and find their properties. They will understand the various geological features e.g. folds and faults. They will be able to select geologically suitable sites for massive Civil Constructions work.
- The overall objective of lecture portion of engineering geology is to demonstrate the importance of
Geology in making engineering decisions specially site selection of engineering projects.
- Introduce the fundamentals of engineering properties of earth materials for their use in civil
- Develop quantitative skills and frame work for solving basic engineering geology problems related to
geological features and geological hazards and remedial measures thereof.
On completion of this course, the students will be able to
- Characterize and classify various minerals and rocks on the basis of their engineering properties.
- Assess geological hazards and develop mitigation frameworks.
- Use seismic and electrical methods to investigate subsurface and develop a native construction plan
incorporating all relevant aspects of geology.
