| 摘 要： | 长洲枢纽建成后只能渠化其上游159 km航道,水浅流急的羊栏滩处于水库脱水段。在贵港至梧州二级航道整治工程中对羊栏滩进行了整治,但未根本改善回水末端的郁江口及羊栏滩河段的船舶双向通航条件,按照《航道整治工程技术规范》(JTJ312-2003),加宽后的设计方案航道尺度根本无法满足设计船队的双线通航要求,严重影响航道的通过能力。文章分析了郁江口汇流段及羊栏滩河床形态和通航水流条件的特殊性,通过物理模型试验和自航船模试验相结合的方法,提出并研究了满足船舶对会的工程方案,并对现行规范中弯道双向航道尺度的计算方法提出了建议。

| Abstract: | Changzhou hydro-junction can only canalize the 159 km waterway of its upstream.Therefore,the navigation obstruction reach of Yanglantan is located in the fluctuating backwater area.The bidirectional navigation condition of the terminal of backwater of Yujiang River estuary and confluence reach of Yanglantan cannot be improved even after the Guigang-Wuzhou second-class channel regulation engineering construction.The channel design dimension in accordance with Technical Code of Regulation Works for Navigation... |
