Question

The failure of slopes may take place due to ___________

(a) Forces between the soil particle and High water content

(b) Action of gravitational force

(c) None of the mentioned

(d) All of the mentioned

I have been asked this question in unit test.

This interesting question is from Stability Analysis of Infinite Slopes topic in chapter Stability of Slopes of Geotechnical Engineering II

Answer 1

Right choice is (a) Forces between the soil particle and High water content

The explanation is: The failure of slopes takes place mainly due to the action of a gravitational force which tends to pull the upper portions of the soil mass downwards to a nearly more level surface.
