Management strategies for Mass movement Flashcards
1
Q
drainage
A
reducing the ground from becoming too saturated and removing excess water-reduces the weight for porous rock
2
Q
vegetating
A
keeps the soil together, compacting and strengthening it. reduces interception and roots stabilise the soil
3
Q
soil nailing
A
keep the soil together on harder rock, strengthening the slope (e.g. on motorways). stops weathering and material from leaving the slope
4
Q
retaining walls
A
stops rocks blocking road on unstable slopes. Reduces movement
5
Q
regrading
A
changes angle of slopes so gravity is less strong (reduces sheer stress)
6
Q
rock bolting
A
holds rock together, making it harder to collapse and fall away
7
Q
Shotcrete
A
spray the rock with concrete to strengthen it
