英语翻译
Small rock fragments and single rock blocks,with sizes
between 0.01 and 1.5 m3,that detach from slopes over-
hanging roads and railways create one of the most frequent
hazards for public transportation systems,and must be ad-
dressed and controlled by the owner of the infrastructure
(Peckover and Kerr 1977; Evans and Hungr 1993).Gener-
ally speaking,protection interventions against rock falls can
be classified as either active or passive:the aim of an active
system is to prevent instability from occurring,whereas pas-
sive systems are designed to mitigate the effects of a pre-
vious movement by intercepting and stopping falling rock
blocks.Pre-stressed wire anchors,rock bolts,and grouted
bars can therefore be classified as active,as they prevent
the detachment of blocks from their original position.Em-
bankments,ditches,net or catch-fences,and rock sheds are
passive,as they do not directly interfere in the process of
rock detachment,but control the dynamic effects of moving
blocks (Peila et al.1998,2006).Wire mesh and cable net
slope protection systems,which are metallic cable nets or
wire meshes installed directly on the slope face (Peckover
and Kerr 1977; Wyllie and Norris 1996; Ferraiolo 2005;
Muhunthan et al.2005; Bertolo et al.2006),can be consid-
ered as systems that are somewhere in between the two
above-mentioned classes:they act mainly by covering the
slope and controlling the movement of rock fragments,thus
preventing them from freely falling onto infrastructure
