Weight-impact test of full-scale rockfall protective soil embankment for grasping rockfall trapping performance

Abstract

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.
