摘　　要：冬季道路除雪日益成为民众关心的突出问题。为了最大限度地减少雪天对道路交通和环境的影响,应当全面提升扫雪铲冰精细化水平,合理处理科学适量撒布融雪剂、快速除雪、安全出行三者之间的关系。结合北京市气象特点和除雪作业方式,选取代表山区路段作为试点,在达到现有除雪作业标准要求下,分析不同融雪剂对道路抗滑性能、土壤盐含量、融冰效果等路用性能的影响。研究结果表明:与氯盐类融雪剂相比,醋酸盐类融雪剂除雪效果明显,但存在用量较大、路面抗滑性能衰减率偏大和雪后抗滑能力偏差的问题。同时,使用不同融雪剂后,土壤中水溶性钠含量、盐含量的增幅均较大,且使用不同融雪剂后土壤均呈现偏碱性的特征。Road snow removal in winter has increasingly become a prominent concern for the public.In order to minimize the impact of snow on road traffic and the environment,it is necessary to comprehensively improve the level of precision in snow sweeping and ice removal,and reasonably handle the relationship among scientific and appropriate application of snow melting agents,rapid snow removal and safe travel.Based on the meteorological characteristics and snow removal methods in Beijing,the mountainous road sections were selected as pilot projects to analyze the effects of different snow melting agents on road anti-skid performance,soil salt content,ice melting effect and other road performance under the existing snow removal standards.The research results indicate that compared with chloride salt-based snow melting agents,acetate salt-based snow melting agents have significant snow removal effect.But there are problems of larger dosage,higher degradation rate of road anti-skid performance,and deviation in anti-skid ability after snow.Meanwhile,he increase in water-soluble sodium and salt content in the soil were more significant,and the soil showed a slightly alkaline characteristic after different types of snow melting agents.
