EOSC 114 Lecture Notes - Shotcrete
Document Summary
Avoidance: move to a different area, avoid problem. Prevention: do something to make sure events don"t occur. Stabilizing slopes (increase resisting forces by adding resisting forces blocks - Anchors (perpendicular to slope, screwed into stable rocks below, tightened at toe of landslide) w/nuts at surface) Drainage (controlling water in a slope is paramount pipes in structure) Braided circle wires (one time use, pretty strong) Protection: armour or strengthen the area that might be affected. Barriers and netting (let"s the fall occur and controls the distance and direction of travel) Separate water and debris by removing debris from the flow with barriers. Prevent more debris from being entrained (concrete lined channel) Decrease flow"s velocity and erosive capabilities (boulder-embedded channel) Large structure looks similar to a dam but designed to catch debris and let water through. Engineered fences made out of woven steel cables and loops. Large bolts drilled deep (~25m) into the rock to secure loose blocks.
