由于灾害强度不断增加，大范围落石灾害的风险也在上升。要求落石对策具有高可操作性、低建设和维护成本。因此，我们重点关注仅由土壤组成的落石防护土路堤。然而，基于性能的土路堤设计方法尚未建立。本研究通过在真实规模的土路堤上进行重量冲击试验，收集落石截留性能的基础数据。根据实尺寸模型试验结果，土路堤的冲击角对落石截留性能有影响。此外，不仅需要研究土路堤的冲击行为，还需要研究口袋的斥力行为。
Because of increasing intensity hazard, the risks of extensive rockfall hazard are rising. Rockfall countermeasures with high workability, low costs of construction and maintenance, are requested. We, therefore, focused rockfall protective soil embankment consisted only by soils. However, performance-based design method of soil embankment is not established. In this study, weight-impact experiment on a real scale soil embankment is conducted to collect basic data for rockfall trapping performance. Based on the results of full-scale model tests, impact angle of soil embankment is influenced to rockfall trapping performance. Furthermore, not only impact behaviors of soil embankment but also repulsion behaviors of pocket is needed to be investigated.
