Abstract

The accelerated development of infrastructure in western China has exacerbated the risk of rockfall disasters. Flexible gabion barriers have been widely adopted as critical protective measures due to their superior adaptability and construction efficiency. However, existing studies predominantly focus on slope stability and retaining wall deformation behavior, while the dynamic response mechanisms of such structures under consecutive rockfall impacts remain insufficiently understood. This study controls the impact frequency of rolling stones and establishes a discrete element numerical model of a flexible gabion barrier structure under continuous impacts at the same collision point. The energy absorption characteristics and stability of the flexible gabion barrier structure under repeated rolling stone impacts are investigated. The results indicate that as the number of rolling stone impacts increases, both the peak impact force and peak displacement progressively increase. This research elucidates the dynamic response differences of the flexible gabion barrier structure under successive impacts and provides guidance for optimizing its design and enhancing its impact resistance.
