《南水北调与水利科技》：南水北调中线穿漳工程模型试验研究（李大志,郭炜,金中武,黄建成）（摘要）

摘要：漳河洪水峰高量大水流湍急，穿漳工程河段滩地宽阔无堤防，为保证工程安全并减少工程对防洪及河势影响，在河势分析基础上，进行了定床模型方案试验，研究比较了涵洞式渡槽和倒虹吸两类5个方案，根据无工程河段水流特点以及工程的影响确定了工程控制点，并通过倒虹吸工程壅水程度与跨度敏感性分析，对工程方案以及工程跨度提出了建议，试验结果表明，工程后断面净河宽达到470m以上时，对设计洪水以及下游河势影响有限。

Abstract:Because of the high flood peak,the large discharge and big current velocity in Zhang River,there is no embankment in open alluvial flat to assure the safety of crossing project and reduce the project effect of flood control and river regime,The fixed bed model test is implemented.5 schemes of the culvert and inverted siphon types are researched and compared.According to the characteristic of stream current and the effect of crossing project,the control point of the project is determined,and through the sensitivity analysis of backwater degree and span some suggestions about the scheme and span of the project are made.The result indicated that the effcet of project on design flood and river regime in the dowm stream is a little,the net river width after project is above 470 m.

Key words:building of crossing Zhang river project;fixed bed model;the backwater of project
