| 摘 要： | 根据西南山区高速公路冰雪影响路段冬季气候特征,选用目前市场上常用的氯盐类融雪剂氯化钠、氯化钾和氯化钙以及有机类融雪剂乙酸钾、乙酸钙,分别在-5,-10和-15℃条件下对这些融雪剂的融雪效果进行试验研究。试验结果表明,在试验温度内,氯盐类融雪剂的总体效果要稍好于有机类融雪剂;乙酸钾与氯盐类融雪剂差别不大;乙酸钙易使冰面出现龟裂和局部松动融化。考虑满足冬季高速公路保通、冰雪影响程度、气温及环保要求,提出了西南高寒山区高速公路冬季养护的融雪剂选择建议。

| Abstract: | According to climate characteristics of alpine areas in southwest China,five deicers including NaCl,CaCl2,MgCl2·6H2O,KAc,Ca(Ac)2·H2O were applied in the ice melting test under the temperature-5℃,-10℃ and-15℃.The result was as follows: chloride deicers generally performed better than acid deicers;there was tiny difference between the melting capacity of the KAc and that of chloride deicers;CaCl2 can cause ice crack and partial looseness.Taking highway mobility,temperature,environmental requirements,and the severity of ice/snow impact into consideration,the deicer in alpine areas in southwest China was proposed in the present paper. |
