摘要 根据宁波地区气象观测站的气象要素和沥青下垫面的温度观测资料,利用多元线性逐步回归方法,得到了晴天、少云、多云和阴雨天气条件下沥青下垫面的日最高温度、最低温度与气象要素特征值的多元回归模型。结果表明:晴天、少云、多云和阴雨天沥青下垫面的日最高温度主要与日最高气温、日太阳总辐射和日平均风速相关;日最低温度与日最低气温线性相关。经检验,模型的预测温度与实测温度相关系数平方在0.91~0.98之间。预测模型对宁波地区沥青层结构物表面的极值温度预佑具有一定的参考价值。 Based on temperature data of meteorological elements and asphalt underlying surface of Ningbo, The maximum temperature and the minimum temperature regression models in sunny, partly cloudy, cloudy and rainy days are set up using the method of multiple linear stepwise regression. Results show that the maximum temperature of asphalt underlying surface is mainly related to daily maximum air temperature, daily total solar radiation and daily average wind velocities ; and a linear correlation is found between the daily minimum temperature and daily minimum air temperature. Upon examination,the correlation coefficient between forecast temperature and measured temperature is in 0.91 -0. 98. The predicting models has something referential value for forecast the extreme temperature on asphalt overlay structure of Ningbo area.
