Maintenance and risk management of rockfall protection net fences through numerical study of deteriorations

Andrea Luciani, Monica Barbero, Daniele Martinelli, and Daniele Peila

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 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.

Short summary
Maintenance of rockfall protection net fences is fundamental for public administrations in order to guarantee risk mitigation. In this paper the influence of deteriorations on the behaviour of this works is analysed using a numerical simulation of the impact of rocks on net fences with different damages. The residual efficiency of a deteriorated net fence is extimated and the resulting variation of the risk mitigation is evaluated. This appraisal allows owners to better plan maintenance works.
