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

摘要

To provide rock fall prevention structureand rock fall prevention method capable of preventing thecollapse of surface layer and preventing the falling of identifiedrock masses. Slope (1) is covered with a net assembly(2) constructed of rope materials (3) and (4) combined inintersectional directions and a wire net connected thereto.The rope materials (3) and (4) of the net assembly (2) areanchored into slope (1) using anchors (6). The anchors (6)are inserted into slope (1) to stabilize a surface layer of theslope (1), giving the anchors (6) and the net assembly (2) astrength able to suppress the movement of identified rockmasses (22) at slope (1). Using the anchors (6) will be ableto prevent the surface layer of slope (1) from collapsingand at the same time, using the anchors (6) and the net assembly(2) will be able to suppress the movement andfalling of the identified rock masses (22) at slope (1).
