What is types of mass movement?Show answer
Mass movement is the downslope movement of rock and soil under gravity. The main types, by mechanism and speed:
What is factors controlling slope stability?Show answer
A slope is stable when the resisting forces (friction and cohesion) exceed the driving force (the downslope component of gravity). Stability is reduced by:
What is triggers of failure?Show answer
A slope close to failure is triggered over the edge by an event that tips the balance:
What is q1?Show answer
State three types of mass movement. [3 marks]
What is q2?Show answer
Explain why water reduces slope stability. [2 marks]
What is q3?Show answer
Name the most effective single engineering measure to stabilise a wet slope, and why. [2 marks]
