Document Summary
What is the mass movement-anything that falls down. What triggers mass movement-earthquakes, volcano and heavy rains. Creep is slope that quietly deform yield to the unrelenting tug of gravity in a slow moving process. Friction and inertia is a mass overcome before something is fails. When something is falls, gravitational pe energy converted to kinetic energy. In what ways are slope failures sometimes obvious. Dipping layer 2- ancient slip surfaces 3-structures within rocks(weak layers,joints) 1)loading slopes, 2)interaction with clay minerals 3) dissolving cement 4)dissolving rocks. 5)subsurface erosion 6-pore water pressure increasing, lowers strength and cohesion. Daylighted bedding-where rock layers are sub parallel to the slope or where they dip at angles less than that of the slope, influences mass movements or slippage. Rotational slide-slope with little layers in it, the whole thing decides to slide on a curved plane and downward and outward movement. Drain the water at the top or porous pipes into the slope to drain it.
