摘　　要：利用2021年10月—2022年9月武汉市长江二桥和二七长江大桥上架设的交通气象自动站的逐分钟气象数据,分析在不同季节、不同天空状况下两座长江大桥的桥面温度变化特征。同时基于统计回归的方法针对两桥分别建立桥面最高温度、桥面最低温度预报模型,模型结果显示预报与实况趋势接近,桥面最低温度的模型准确率较高,具有良好的实际应用价值;而桥面最高温度的模型准确率较差,实际应用中需要适当进行订正。Based on minute-scale meteorological data from automatic meteorological stations set up on Wuhan No.2 Yangtze River Bridge and the Erqi Yangtze River Bridge from October 2021 to September 2022,this research analyzes the characteristics of the temperature variation of the bridge deck of the two Yangtze River bridges under different seasons and sky conditions.At the same time,based on the statistical regression method,the forecast models of the maximum and minimum bridge deck temperatures of the two bridges were established respectively.The results show that the forecast is close to the actual trend,and the model of the minimum bridge deck temperature has a higher accuracy,which has good practical application value;while the accuracy of the model of the maximum bridge deck temperature is poor,and it needs to be corrected appropriately in practical applications.
