公路工程

在现有大体积混凝土冷管控制的基础上,对某连续刚构桥大体积混凝土承台(12.4 m×12.2 m×4m),采用有限元软件从冷水管的间距、流量和类型3个方面了进行方案优化,并将优化结果与原始方案进行对比分析,分析结果表明冷水管的间距、流量和类型都会影响冷管的降温效果,最后得出针对该工程的最佳冷管控制方案。提出的冷管控制方案及分析计算方法为今后同类工程提供了有用的参考依据,也为今后开展深入理论研究提供了基础。

In this article,on the basis of the existing large volume of control on the cold concrete,on a continuous rigid frame bridge massive concrete pile cap( 12. 4 m × 12. 2 m × 4 m),using the finite element software,conducting optimization from the cold water pipe spacing,traffic and the type of the three aspects,and program optimization results were compared with the original,the results show spacing cold water pipe,the flow and type will affect the cooling effect of the cold pipe. Finally,optimum cooling tube control scheme for the project. Cold and calculating method of control schemes analyzed in this paper provide a useful reference for similar projects in the future and a useful reference for similar projects in the future.
