Abstract:
The research on landslide-generated impulse waves has evolved from scientific understanding and predictive analysis to risk prevention and control, which is an inevitable requirement for disaster prevention and mitigation. This paper reviews the methods, engineering measures, and mechanisms of impulse wave prevention and control in a systematic way, following the evolution stages of landslide-generated impulse waves. At the landslide wave generation stage, landslide control measures to reduce wave generation capacity are summarized; sloped, vertical wall, and floating breakwaters can be used to dissipate propagating waves, with the main functions of blocking, reflecting, and dissipating impulse wave energy; different types of seawalls have different mechanisms to block run-up waves. According to the conditions such as landslide status, landslide-generated impulse wave risk prevention and control can adopt four methods: avoidance, retention, transfer, and loss control. Specific measures include site planning, utilization and remediation, prevention planning and monitoring and early warning, impulse wave risk reduction engineering, impulse wave early warning, and emergency evacuation, et al. This paper elaborates on the major challenges faced by landslide-generated impulse wave risk prevention and control, and points out the direction for the development of research on the prevention and control of landslide-generated impulse waves.
