某干旱及大温差地区公路温差气候区划研究

Research on climatic regionalization of the highway in arid area with large temperature difference

根据新疆维吾尔自治区干旱大温差的气候特点,利用气象年极端最低气温、7月平均最高气温、年降水量及潮湿系数对新疆地区100多个观测点数据进行分析,将干旱温差强度分为轻度、一般、重度及特大4个等级,这一分区对公路沥青路面的设计与施工有据可依,具有实用价值。

According to the climate characteristics of Xinjiang arid area with large temperature difference, the three meteorological elements： annual extreme minimum temperature in July, the average maximum temperature, annual precipitation and wet coefficient of these factors, are collected from more than 100 observation stations of Xinjiang for data analysis. The arid and temperature strength is divided into 4 grades.mild, general, severe and large, from which the results on Xinjiang highway asphalt pavement provides the design and construction with practical value.
