公路用融雪剂理论用量研究

Research on the Theoretical Amount of Snow-melting Agent for Highway

文章提出了采用融雪剂冰点标准曲线,确定不同气温条件下融雪剂理论用量的方法。研究认为,以冰点标准曲线确定融雪剂用量,需综合考虑温度和需要融化的冰雪量。在融雪剂应用过程中,实际用量亦受其他次要因素影响,如融雪剂融化冰雪时的热效应、光照、风速、蒸发、撒布时机、交通量、交通开放要求等。同时提出确定融雪剂理论用量的方法,从而最大限度地发挥融雪剂融雪化冰的作用,为融雪剂的科学使用提供案例参考。

The method of using the freezing point standard curve of the snow-melting agent to determine the theoretical amount of the snow-melting agent under different atmospheric temperature conditions is put forward.The research shows that,it is necessary to comprehensively consider the temperature and the amount of ice and snow needing melting by using the freezing point standard curve to determine the amount of the snow-melting agent.In the application process of the snow-melting agent,the actual amount is also affected by other secondary factors,such as the thermal effect of the snow-melting agent for snow and ice melting,illumination,wind speed,evaporation,spreading timing,traffic volume,traffic opening requirement and so on.At the same time,the method to determine the theoretical amount of the snow-melting agent is put forward,so as to maximize the effect of the snow-melting agent for snow melting and deicing,and provide the case reference for the scientific use of the snow-melting agent.
