Steel Baffles as a Rockfall Protection Measure for Mountainous Urban Settings

A form of steel baffles, which is made poles encased in concrete and embedded into the ground, are introduced this article. This type protective installation to be located on previously identified/designed catchment at multiple levels up hillslope fence off large fallen boulders during landslides or rockfalls. These baffles intended serve as added-on protection filter barriers (array baffles) that have recently gained popularity a means filtering out coarse debris. The aforementioned devices installed strategic positions close unstable rocks (noting velocity impact can much reduced upstream end rockfall trajectory). proposed design involves only simple hollow section, ground. process manually excavating hole ground accommodate baffle, followed by backfilling with concrete. straightforward calculation method, found established principles structural dynamics soil mechanics, has been developed determine section sizes embedment depths for given scenario. Based presented procedure, set charts expediting analysis process. methodology based use validated comparison data generated LS-DYNA simulations.
