| 摘 要： | 通过水工模型试验研究了三峡枢纽不同运行时期的坝区水流结构变化特点。研究表明,坝区水流结构与河势演变后形成的河床形态基本相对应。当水库运行50+4a后,在口门区及连接段一带弯道水流特点明显,并出现主流摆动的现象。

Analysis on Flow Structure of Dam Area of the Three Gorge Project During Flood-discharge |
| |
| Abstract: | From hydraulic model test, varying characteristics of the flow structure of the dam area during the different running periods of the TGP are studied. It s shown that the flow structure in the dam area are basically corresponding with the bed configuration after evolution of the river situation. When the TGP has run 50 + 4 a, the characteristics of the winding flow will be obvious and the main flow wiggling will occur at the entrance and the connecting section of the channel. |
