The Effect of Rockfall Rotational Motion on the Energy Absorption Characteristics and Rockfall Capture Performance of Rockfall Protection Soil Embankments

Puntos clave

• This research aims to investigate how the rotational motion of rockfall influences energy absorption and capture performance of soil embankments.
• Conducted impact experiments using weights with and without rotational motion.
• Measured deformation near collision areas and overall energy absorption of embankments.
• Analyzed the effects of rotational rockfall on capture efficiency.
• Soil embankments effectively absorbed impact energy regardless of rotational motion.
• Rotational motion of weights reduced capture efficiency due to pronounced ramp-up behavior.
• Increasing slope steepness was quantitatively demonstrated to be an effective control method for ramp behavior.
