Question
A 30 meters high natural rock
slope has a slope face dipping
at an angle of 60 degrees. A
bedding plane dipping 25
degrees in the same direction
with the slope face daylights
on the slope face, making a
plane slide kinematically
permissible. A tension crack
was located at 16 m behind the
crest of the slope, and it has a
depth of 14.4 m. The rock has
unit weight of 26 kN/m3 and
friction angle of 40 degrees
with zero cohesion. What is
the Factor of Safety of the
slope against plane sliding
when the crack is filled with
water during prolonged
rainfall? Use unit weight of
groundwater equal to 9.81
kN/m3.
