箱梁温度场的影响因素分析

Numerical analysis of box girder temperature field of the thermophysical parameters of concrete

以广佛高速公路跨线桥主桥为背景工程,连续9个月对混凝土箱梁进行温度场观测,获取大量的实测数据,由此建立箱梁温度场分析模型,研究混凝土热物理参数及铺装层对温度场的影响。

Based on a great deal of measured data obtained through the continuous nine-month observation of the temperature field of the concrete box girder of the Guangzhou-Foshan freeway overpass bridge, a temperature field analysis model for box-girder is established. How thermophysical parameters and concrete pavement influence the temperature field is also studied by using the model.
