固定自动喷淋冰雪抑制技术在北美和欧洲的应用

Application of Fixed Automated Spraying Anti-icing Technology in the United States of America and Europe

为解决道路和桥面因雨雪冻结引起的交通难题,介绍了一种国外防冰技术——固定自动喷淋技术(Fixed automated spray technology,以下简称FAST)。总结了FAST系统的组成、工作流程、优缺点和维护问题,并分析了FAST系统在北美和欧洲的应用实践情况。FAST系统是关键位置防冰的一种重要方法,能够针对性地对冰雪来临之前的潜在的问题进行预防,促使道路和桥面冬季防雪化冰模式从被动向主动转变,为我国道路和桥面防冰技术的研究与今后国内类似的工程项目提供参考。

In order to solve the traffic problem caused by ice and snow,this paperintroduced a foreign anti-icingtechnique--Fixed automated spray technology（referred to FAST）. FAST system composition, working process, advantages and disadvantages, and maintenance problems of FAST were summarized. Practical applications of FAST system in North America and Europe were analyzed. FAST system is an important anti-icing method in the key position ,which can prevent potential problems pertinently before the coming of the ice and snow. It can also promote anti-icing pattern to change from passive to active transition, and provides reference for the study of anti-icing technology on road or bridge or similar projects in the future.
