A STRUCTURE FOR PREVENTING ROCKFALL, A ROCKFALL PREVENTION METHOD, AND A METHOD FOR DESIGNING SAID STRUCTURE

摘要

To provide rock fall prevention structure and rock fall prevention method capable of preventing the collapse of surface layer and preventing the falling of identified rock masses. Slope (1) is covered with a net assembly (2) constructed of rope materials (3) and (4) combined in intersectional directions and a wire net connected thereto. The rope materials (3) and (4) of the net assembly (2) are anchored into slope (1) using anchors (6). The anchors (6) are inserted into slope (1) to stabilize a surface layer of the slope (1), giving the anchors (6) and the net assembly (2) a strength able to suppress the movement of identified rock masses (22) at slope (1). Using the anchors (6) will be able to prevent the surface layer of slope (1) from collapsing and at the same time, using the anchors (6) and the net assembly (2) will be able to suppress the movement and falling of the identified rock masses (22) at slope (1).
