Question

Discuss various favorable and unfavorable conditions in some different types of engineering rocks.

Answer 1

The most favorable situation in various rocks like Andesite.Basalt.Dacite.Diabase.Diorite.Gabbro. Granite.Obsidian. is when rocks dipping against the slope,

while most unfavorable condition will be when rocks dip towards slope.

If the hills have horizontal or vertical rocks, the slope created will have almost similar conditions all around the hill.

The dipping rocks will have different conditions around the hill i.e. in hill face perpendicular to strike of rocks will dip towards the slope, opposite to this face rocks will dip against the slope while in rest of the sections, rocks will show varying angles of dip (apparent dips) and may look apparently horizontal on slopes running parallel to its strike.
