| Abstract: | The second stage river closure is one of the main technical problems forthe Three Gorges Projed. To solve the prthlems of the deepwater river closurig in largeflood and the permileing of navigation in this period, The hydraulie experiment have beenperformed in the 1: 100 and 1:80 whole structure models and 1: 40 sectional model ofYangtze River Scientific Research Institute, It involve: the choices of time and vnlume offlood, the sile and width of the finAl gap. the comparison between vertical closure and flatblocking up before closure, the navigation condition and the hydraulie condition thebanquette collapsing and protection measures etc. Partial results are presented briefly inthis paper. |
| Keywords: | River closure the final gap Navigation banquetlie collapsing Flat block up |
