| 摘 要： | 采用平面二维水流数学模型,对南水北调东线某工程调水分流区通航水流条件进行了计算分析,提出了改善通航水流条件的方案.计算结果表明,现状条件下分流区通航水流条件不能满足规范要求,方案2通过扩挖金宝河及分流区南侧对回流区和横向流速的改善效果较好,推荐其作为工程改善措施.

| Abstract: | The water conditions for navigation in a distributary domain of the Eastern Route of South-to-North Water Transfer Projectiscomputed and analyzed with atwodimensionalmathematicalmodel.Measures for improving the navigable water con-ditions are proposed.The computed results indicate that the water conditions in the distributary domain under the present situa-tion can not meet the requirements of the standards.Plan 2 may produce satisfactory improvement of the water conditions in the return flow zone and the t... |
