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?
