摘要：	Rapid and extreme climate change is putting our planet under stress. As a consequence, in. mountain and hilly regions, infrastructure and people are more often threatened by quick and unpredictable rockfall events. Falling boulders can have extremely high speeds, exceeding 11 mph (5 m/s) and up to 67 mph (30 m/s); these events involve a complex pattern of movement (e.g., detachment, fall, rolling, sliding, bouncing) of one or more rock fragments. Rockfall protection embankments (RPEs) have proven to be a safe measure for protecting people, structures and infrastructure from rockfall events (Figure 1). These mitigation measures can be done as unreinforced or reinforced earth embankments and designed to absorb medium- to high-energy impacts (1,000-30,000 kJ). Depending on their construction, these structures may also withstand multiple impacts. RPEs can be constructed in various shapes and sizes to suit the site, and with a range of internal reinforcing elements and facing materials (soil, riprap, cushion facing). They work through a combination of deformation and internal compaction to absorb the energy imparted by falling rock blocks. They have been used since the 1970s, and many research programs have been executed with a focus on improving their design and ability to resist the impact.
