Abstract
Slope disasters such as slope failures often occur in Japan due to various natural phenomena. Shotcrete and other slope works are carried out to protect social infrastructure and dwellings from slope disasters. Lifelines and safety belts are used to prevent falling accidents and ensure the safety of the workers who engage in slope works. A number of standard lifeline fixing methods are widely used and reported, but their engineering rationale is unclear. In the present study we considered the proper diameters, driving depths, and shapes of the anchors used to fix lifelines, in order to prevent friction and wear of the lifelines and better maintain safety during work on slopes. This paper reports the results of an impact loading experiment performed with experimental banking simulating a construction work site on a slope.
