大型渡槽温控研究成果与应用

Research Results and Application of Temperature Control of Large Aqueduct

随着我国国民经济的发展，我国水源分布不均衡性越来越突出，大规模、长距离、跨流域的调水已经是解决该问题的重要方法和手段，目前正在修建的南水北调工程沿线布置了许多渡槽，渡槽结构为薄壁高性能混凝土结构，温控防裂要求高，现对南水北调磁县段工程渡槽温控研究与实际建设过程中应用情况进行了介绍，以利于其他类似工程参考。

With the development of national economy, water shortage has become increasingly severe. Water diversion of large-scale, long dis- tance,and inter-basin is an important means to address the issue. Currently many aqueducts are built along the South-to-North Water Transfer Project. As aqueduct structure usually is thin-walled high-performance concrete structure, its anti-crack requirements of temperature control is high. This paper has introduced some researches on the aqueduct＇s temperature control in Cixian County section of the South-to-North Water Transfer Project and actual construction process, which is conducive to other similar engineering for reference.
