Abstract

Trains and railway infrastructure are subjected to serious potential hazards from detached falling rock(s) in mountain regions worldwide. This can lead to severe damages, casualties and significant delays. In 2011, a rockfall event at Stromeferry bypass in Scotland caused 4 month railway closure that led to a negative impact on local businesses and the repair work cost was £3.2 million. Rock catch fences are widely used in protecting roads, railways and infrastructure from rockfall hazards. A typical design comprises of a high tensile strength wire mesh that is anchored to the ground by rigid posts and strengthened to the lateral and upslope sides by anchoring tension cables. These systems are categorised by the ability to dissipate the kinetic energy of falling rock(s). Due to the lack of a practical design code, these systems are designed primarily by experience and engineering judgement, which makes the design either dangerous or highly conservative. Indeed, engineers found that the current design tend to be highly conservative which makes the costs for materials and construction too high. There is an urgent need to improve the current design based on extensive experimental tests and advanced finite element modelling. This study presents the development of a lightweight rock catch fence design.
