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.
