摘　　要：现行桥梁规范对单层混凝土铺装桥梁提供了单一的梯度温度参数,难以适应全国不同地域。为探究一种更符合闽南地区水泥混凝土铺装箱梁的温度场计算公式和参数,以闽南地区五地市近30年的气象数据,拟合出主要气象参数的超越概率曲线,计算得到各气象参数50年一遇标准值;利用GeoStudio的TEMP/W模块进行温度场有限元数值分析,得出水泥混凝土铺装箱梁的温度梯度曲线公式,为闽南地区水泥混凝土铺装箱梁的温度场选定提供参考。The current bridge code provides a single gradient temperature parameter for single-layer concrete paved bridges,which is difficult to adapt to different regions in China.In order to explore a more suitable formula and parameters for temperature field calculation of cement concrete paving box girder in Southern Fujian,the exceeding probability curve of main meteorological parameters was fitted based on the meteorological data of five cities in Southern Fujian in recent 30 years,and the standard values of meteorological parameters with 50 year return period were calculated.The temperature field finite element numerical analysis was carried out by using the TEMP/W module of GeoStudio,and the cement concrete pavement was obtained.The temperature gradient curve formula of box girder can provide reference for temperature field selection of cement concrete paving box girder in Southern Fujian.
