摘　　要：湍河渡槽是南水北调中线关键控制性工程之一,针对其长度大、流量大的特点,设计首先确定了槽身布置方式、渡槽长度及跨度,然后选定了双向预应力梁式渡槽为其结构形式。详述了渡槽结构计算分析结果和1∶1模型试验过程。分析表明,渡槽结构的计算方法选用基本正确,其计算结果与模型试验结果基本一致,槽身基本处于全受压状态,工作状态良好。介绍了造槽机的施工方案及布置情况。The Tuanhe aqueduct is a key controlling project in Middle Route Project of South-to-North Water Diversion. According to its characters of long distance and large flow, the engineers firstly determine its length, layout and span, then the structural formation of double pre-stressed beam aqueduct is proposed. The structural calculation results and 1：1 model test process are presented in detail. The results show that mechanics calculation method adopted is basically correct and the calcula-tion results are in agreement with the model test, in which the aqueduct body is in compression state in general and in good work-ing situation. Finally, the construction scheme and layout using aqueduct fabrication machine is presented.
