| 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. |
