Slope Stability

Question 1

What is plane failure

Answer 1

when the general conditions lead to it sliding on a plane
(dip of plane greater than friction angle of plane)

Question 2

what is a rotational (circular) failure

Answer 2

where the overburden of soil waste rock or heavily fractured rock with no idenifiable structure or pattern fails. This can be in soil slopes, waste dumps and stockpiles.

Question 3

what is a wedge failure

Answer 3

failing when a wedge forms from at least two defects strike across the slope crest

Question 4

what is a toppling failure

Answer 4

in hard rock that forms column structure separated by steeply dipping discontinuities

Question 5

study fs calculations

Answer 5

will likely be in the exam
