摘要： 铜锣峡是三峡库区回水变动段内典型的峡谷河段,其洪水急流滩特性阻碍了万吨船队在水位消落期的顺利航行.本文利用平面二维水流数学模型,通过水位和流场验证后,对建库后铜锣峡河段的航行条件进行了模拟.进行窄深和宽浅两种挖槽型式的整治工程后,计算分析表明,宽浅型挖槽更适用于该类型滩段.同时,对成滩和通航流量进行了分析.

Abstract: Tonglexia reach is a typical gorge reach in variable backwater zones of the Three-Gorge reservoir region.Its features of rapids in high level block sailing of ten-thousand-ton fleet in the period of low level.This paper has made use of two-dimension mathematics model.Water stage and velocity field were rightly verified.Sailing condition of Tonglexia reach after reservoir built was modeled.Two kinds of regulation measures, narrow-deep and wide-shallow excavation, were calculated.Results show wide-shallow excavation is more suitable for regulation of gorge reach.In addition, we have analyzed shoal and sailing discharge.
