三峡工程导流明渠截流模型试验跟踪预报及实施

 三峡工程明渠截流实施期间,水工模型试验全程跟踪原型施工。结合水文水情预报、边 界条件、施工进度对截流水力学指标的影响等问题进行了大量的试验研究,向业主、设计、施工单位提供了大量的跟踪预报试验成果,对原型、模型数据进行了对比总结。这显示出对截流施工的科学化、信息化的管理水平,证实了模型试验的相似性和对施工的指导作用。

Model pursuit,forecast and construction practice on TGP's diversion channel closure

During the TGPs third stage river closure, hydraulic model tests pursued field construction all the time. Based on hydrologic regime forecast, lots of model tests on the influences of all kinds of boundary conditions and construction progress on hydraulic parameters such as velocity, drop etc., were performed, and the test results were provided for the proprietor, desi gners and the construction corporation. The data of imodel test and prototype observation were compared and analysed. The entire process revealed the management level of applying advanced information technology, and the results verified the similarity of model test and its guide significance to construction.
