Abstract
This paper presents full scale experiments of falling rock protection nets by using full scale falling rock collision test facilities. 4 types rock models, i.e. 0.35 to 2.5 ton in weight, and 6 types of collision energy parameters, i.e. 20 to 28 kJ, made by slopes set at vacant quarries are used. 4 types of real size nets, i.e. 5×15 to 15×30m are used as specimens. The dynamic deformation process of net are recorded by video and high speed camera, and the tensions of anchorage wire-ropes are measured by load cells. Experimental results are discussed from viewpoint of design code used in general.
