Snow avalanche is one type of the largest natural hazards in alpine regions. Because of the monitoring and warning technology is still not perfect at present, developing hazards prevention and control technologies is an important measure to reduce the human life and property loss that cause by snow avalanche. In this paper, some in- ternational commonly used prevention and control technologies are classified. The research progress, application scope, design requirement, application situation of these technologies are summarized and discussed. What' s more, the paper points out that there are some shortages such as lack of construction standards, avalanche mecha- nism is not el'ear, parameters calculation of engineering design is unreasonable, the effect of test simulation is not perfect, the basic theory research is behind the practice activities and so on. Finally, the paper proposes several aspects for future research.
