Part A is compulsory (25 Marks). Part B: Answer any one full question from each unit (50 Marks).
Part A
Define Geology? How it is useful to civil Engineering aspect?
Answer
Geology is the branch of earth science that deals with the study of the Earth's composition, structure, physical properties, and the processes acting upon it. In Civil Engineering, it is essential for assessing site suitability, selecting construction materials, ensuring foundation stability, and mitigating risks from natural hazards like landslides or earthquakes.
What are the geological draw backs of the constructions?
Answer
Geological drawbacks that can compromise construction include:
- Presence of faults, joints, or shear zones that reduce rock mass strength.
- Differential settlement caused by heterogeneous soil or rock layers.
- High permeability of subsurface strata leading to water leakage or piping in dams.
- Susceptibility to slope instability and landslides in hilly terrain.
