Background

The avalanche is a common natural phenomenon and is widely distributed in snowy mountainous areas with medium, high latitude and high altitude, and is mainly distributed in snowy and mountainous areas such as Sinkiang, Gansu, Qinghai, Tibet, Sichuan and Yunnan in China, while Sinkiang is mainly concentrated in Tianshan areas. The occurrence of the avalanche frequently causes various natural disasters, influences the surrounding natural environment and the human society to different degrees, and has great harmfulness. In avalanche prevention, the current major engineering management measures can be classified into 4 types according to functions: snow stabilizing engineering, also called snow supporting engineering, such as snow stabilizing fences, snow rakes, snow nets, snow stabilizing walls and the like; secondly, snow guiding engineering, such as snow guiding walls, snow guiding dams, snow protection corridors and the like; thirdly, snow-resisting engineering, such as snow-retaining hills; and fourthly, directly protecting engineering, such as a snow protection corridor. Or a comprehensive treatment measure combining the engineering treatment modes.
