Rock Falls Impacting Railway Tracks: Detection Analysis through an Artificial Intelligence Camera Prototype

الملخص EN

During the last few years, several approaches have been proposed to improve early warning systems for managing geological risk due to landslides, where important infrastructures (such as railways, highways, pipelines, and aqueducts) are exposed elements.

In this regard, an Artificial intelligence Camera Prototype (AiCP) for real-time monitoring has been integrated in a multisensor monitoring system devoted to rock fall detection.

An abandoned limestone quarry was chosen at Acuto (central Italy) as test-site for verifying the reliability of the integrated monitoring system.

A portion of jointed rock mass, with dimensions suitable for optical monitoring, was instrumented by extensometers.

One meter of railway track was used as a target for fallen blocks and a weather station was installed nearby.

Main goals of the test were (i) evaluating the reliability of the AiCP and (ii) detecting rock blocks that reach the railway track by the AiCP.

At this aim, several experiments were carried out by throwing rock blocks over the railway track.

During these experiments, the AiCP detected the blocks and automatically transmitted an alarm signal.
