北方积雪从自然积雪到压实积雪的密度变化范围为0．1～0．7g／cm^3，硬度变化范围为0～60kgf／cm^2，而冰的密度接近于1．0g／cm^3，硬度范围则为150-300kgf／cm^2，远远大于一般积雪。所以相比而言，清除密度较小、硬度较低的松散自然积雪和轻度压实雪要比清除坚硬压实积雪容易得多，而清除冰层的难度更要增大数十倍、上百倍。
According to recently widely used mechanical snow removal and deicing methods,the throwing, shoveling,brushing,milling and the combination styles of machines are systematically introduced. Basic structure,working principle,applicable circumstance,advantages and disadvantages are expounded respectively,which provides reference for snow removal and deicing of pavement in the upcoming winter.
