A fiber Bragg grating (FBG) tension sensor for anchor rope has been proposed and implemented in the full-scale impact test of rockfall protection barriers in this paper. According to the measurement principle of the tension sensor, the wavelength shift difference of the two FBGs which, respectively, measure the positive and negative strain in the spring element is utilized as sensing signal. Therefore, the force sensitivity is increased and the temperature cross-sensitivity is compensated. Experimental results indicate that the measurement sensitivity is 14.85 pm/kN in a range from 0 to 150 kN. The dynamic forces on anchor ropes in barriers have been clearly recorded by the designed sensors during the impact test, and the variation of the impact forces could be mainly divided into three stages. This kind of tension sensor is expected to be widely used for force's quasi-distributed measurement or remote monitoring in industrial and mechanical fields.

“…The major improvement related to GIS or/and the use of DEM is the automatic kinematical analysis (Wagner et al, 1988;Rouiller et al, 1998;Gokceoglu et al, 2000;Dorren et al, 2004;Günther, 2003;Guenther et al, 2004), which allows one to determine whether the discontinuity sets are able to create instabilities. Using the standard stability criterion (Norrish and Wyllie, 1996) and a statistical analysis of the kinematical tests, Gokceoglu et al (2000) were able to produce maps of probability of sliding, toppling or wedge type failures.…”

Abstract. Rockfall is an extremely rapid process involving long travel distances. Due to these features, when an event occurs, the ability to take evasive action is practically zero and, thus, the risk of injury or loss of life is high. Damage to buildings and infrastructure is quite likely. In many cases, therefore, suitable protection measures are necessary. This contribution provides an overview of previous and current research on the main topics related to rockfall. It covers the onset of rockfall and runout modelling approaches, as well as hazard zoning and protection measures. It is the aim of this article to provide an in-depth knowledge base for researchers and practitioners involved in projects dealing with the rockfall protection of infrastructures, who may work in the fields of civil or environmental engineering, risk and safety, the earth and natural sciences.

“…Sci. MEL and SEL tests were simulated on the numerical model of the net fence and the results of these simulations were compared to those of the real scale MEL and SEL tests reported by Gottardi and Govoni (2010). As can be seen from Table 1, the numerical model well reproduced the results of the real scale tests.…”

Abstract. Rockfall protection net fences are key protection systems in mountainous areas worldwide to ensure the safety of infrastructures, roads and urban areas against rockfall. Management of the maintenance of rockfall protection net fences is fundamental for public administrations in order to guarantee risk mitigation. This paper deals with the assessment of the 10 installation problems and deterioration of rockfall protection net fences, using numerical modelling in order to evaluate the influence of these issues on their behaviour. A percentage of the residual efficiency is assessed as a useful tool for risk analysis and maintenance planning.
