Assessment of Protection Systems for Buried Steel Pipelines Endangered by Rockfall

The potential of two different protection systems for rockfall endangered steel pipelines was assessed in this paper. The first protection system consists of an overburden of the pipe made of sandy gravel. Based on one real scale impact experiment into a gravel buried steel pipe, the developed structural finite element (FE) model was assessed. In regions where the highest loading of the steel pipe occurs, the developed structural model yields satisfactory results. In case of the gravel based protection system (GBPS), both damping of the impact and load distribution and load carrying capacity to reduce the loading of the steel pipe are performed by gravel. For the second protection system, an enhanced protection system (EPS) is proposed. It consists of (i) gravel as an energy absorbing and impact damping system and (ii) a buried steel plate supported by concrete walls as a load carrying structural component.
