三峡工程明渠导流通航及数值实验研究概述

通过三峡工程导流明渠导流通航研究及实践，在巨大导流流量和极高通航水流条件下，导流明渠满足了客货轮的通过能力，成功地解决了弯道上明渠导流及施工通航的关键技术问题。在对导流明渠的研究中，运用了小尺度自航船模试验、水流特性数值实验室模型等有关明渠导流及通航的创新技术，改进了明渠体形，解决了特殊情况下明渠通航条件问题。

The research of the navigation and diversion in TGP channel and its numerical simulation

Through the research and the implementation of the navigation of the d iversion channel in TGP, and under the conditions of huge river diversion discha rge and extremely high navigation stream, the diversion channel satisfied the tr ansit capacity of passenger and goods and successfully solved the key technologi cal problems of the river diversion and the construction navigation. This articl e introduces several key technologies of the river diversion and the navigation, such as the new technology by using little dimension self-propelled boat model test to solve the navigation problems, the forms of the diversion channel and na vigation, the navigation condition of the diversion channel under special situat ion, the flow characteristics numerical experimental lab of the diversion channe l etc.
