Question
1. Telluride site at 8750 feet in the Rocky Mountains. Identify the climate factors that would most likely promote slope failure. Select all that apply
2. In identifying the tectonic phenomena that would most likely trigger slope failure. Is this statement true or false for the location: The mountains have been lifted by endogenous tectonic forces that could trigger an earthquake, which could in turn trigger slope failure.
Daily freeze-thaw cycles would form talus slopes with abundant loose rock.Explanation / Answer
STEP 1
Slope failure occurs when the downward movements of material due to gravity and shear stresses exceeds the shear strength. Therefore, factors that tend to increase the shear stresses or decrease the shear strength increase the chances of failure of a slope. Different processes can lead to reduction in the shear strengths of rock mass. Increased pore pressure, cracking, swelling, decomposition of clayey rock fills, creep under sustained loads, leaching, strain softening, weathering and cyclic loading are common factors that decrease the shear strength of rock mass. In contract to this the shear stress in rock mass may increase due to additional loads at the top of the slope and increase in water pressure in cracks at the top of the slope, increase in soil weight due to increased water content, excavation at the bottom of the slope and seismic effects. In addition to these reasons factor contributing in failure of slope are properties of rock mass, (slope geometry), state of stress, temperature and erosion.
Telluride site at 8750 feet in the Rocky Mountains. Identify the climate factors that would most likely promote slope failure is The warm humid tropical climate would encourage mudflows.
