三峡工程下引航道水沙运动数值模拟

A Mathematical Model of Water and Sediment Motion in the Lower Entrance Channel of the Three Gorges

本文在以往研究的基础上建立了能模拟三峡下引航道水沙运动规律的数学模型,探讨了三峡下引航道在连续五级和分散三级两类船闸布置方案下的水沙运动规律及如何削弱水位波动,减少泥沙淤积等问题,并比较了两类布置方案的优劣,所得结果可供工程设计参考。

Based on the previous research, a mathematical model simulating the motion law of water and sediment of the Three Gorges lower entrance channel is established in this paper. The law of water and sediment movement in two design schemes of the ship locks of the Three Gorges lower ontrance channel is studied. One of them is of continuing five grades and the other is of separate three grades, The problems of decreasing sediment deposition and increasing navigation depth are discussed and the difference between the two design schemes is discussed too. The results obtained may provide a reference for hydroproject design.
