| 摘 要： | 通过沥青摊铺施工过程中在梁体竖向、桥梁纵向和桥梁横向三个方向产生不均匀温度分布情况,结合工程实际进行研究。文章分析了沥青摊铺的影响深度、箱梁达到最高温度的滞后时间、箱梁各部位的升温速率等时空分布规律,同时提出摊铺过程中桥梁纵向、横向不均布温度分布可忽略,各个断面可单独进行温度场的平面分析。

| Abstract: | During the construction process,the asphalt paving can produce the uneven temperature.The author did the related research with the practical engineering.The paper analyses the time-space distribution rule about the box girder in the condition of the asphalt paving.It contains the influencing depth,the time leg and the heating rate.It puts forward that the longitudinal uneven temperature distribution and the transverse uneven temperature distribution is neglectful,and each section can do the plane analysis o... |
