Question

1. There is an infinite slope located in Arequipa with an
inclination of 34 ° and the rocky substrate is 17 meters deep. Soil
in the dry state has the following characteristics: density = 1.8 g
/ cm3, cohesion = 0.65 kg / cm2, internal friction angle = 31 °;
and in the submerged state: saturated density = 2.3 g / cm3,
effective cohesion = 0.25 kg / cm2, effective internal friction
angle = 27 °.

a) Find the stability of the slope in dry condition.

b) Find the stability of the slope in saturated condition.

c) If an earthquake occurs at the site, what will be the safety
factor for the dry slope with earthquake?

Answer #1

Course: Soil mechanics
Theme: Fellenius Method
Determine the stability of a slope and the Critical Height, if the
weathered fraction is 35 m and the following effective soil
properties were determined. Unit weight 1.32 g / cm3, the angle of
friction of 19 °, effective cohesion of 0.35 kg / cm2, the slope of
the slope is 23 °

An infinite slope of 5m height has following
properties. Voids ratio = 0.32, Specific gravity = 2.65 and Degree
of saturation = 50%, Angle of slope of 20°, cohesion = 25kPa and
angle of internal friction of 28°. Determine the
following.
The factor of safety for submerged
condition.
The factor of safety if the water table is at 1.5m
from top surface of the slope.
Height of the dry slope if the factor of safety after
construction is 3.

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
