Part A
What is the importance of structural geology in civil engineering?
Answer
Structural geology is crucial for assessing the stability of rock masses. It helps in identifying discontinuities like folds, faults, and joints, which significantly influence the selection of sites for dams, tunnels, and bridge foundations by determining the potential for rock failure or leakage.
What are the geological draw backs of civil engineering?
Answer
Geological drawbacks include the presence of weak or unstable rock formations, high permeability causing water seepage, seismic activity (earthquakes), presence of faults or joints that reduce rock strength, and the occurrence of landslides or slope failures that threaten structural integrity.
