摘要
通过对高原山区公路冬季温度湿度数据变化规律的研究,以及路面结冰预测模型的分析,结果显示:(1)路面温度和湿度与大气温度和湿度变化规律基本相同,两者差值温度在1℃左右、湿度在5％左右,证实了采用路面温度和湿度来分析路面结冰状态是可行的;(2)分析了路面结冰时间与对应路面温度和湿度数据,提出了利用智能温度和湿度数据来预测路面结冰的理论,以及路面结冰预警信息;(3)建立了公路路面结冰预测模型,提出了高原山区冬季公路路面结冰预测模型的阀值,为冬季智慧养护决策提供了可靠的数据支撑.
Abstract
The changes in winter temperature and humidity data of highways in plateau mountainous areas are studied,and road surface icing prediction models are analyzed.The results show that:(1)the changes in road surface temperature and humidity are basically the same as those in atmospheric temperature and humidity,with a difference temperature of about 1℃ and a humidity of about 5％,which confirms the feasibility of using road surface temperature and humidity to analyze road surface icing status.(2)The time of road icing and the corresponding road temperature and humidity data are analyzed,the theory of using intelligent temperature and humidity data to predict road icing as well as road icing warning information is proposed.(3)A prediction model for road surface icing is established,and the threshold values for the winter road surface icing prediction model in plateau mountainous areas are proposed,providing reliable data support for intelligent maintenance decision-making in winter.
