| 摘 要： | 利用平面二维水流数学模型，对淮河入海水道淮安地涵构纽下游河道连接段水流进行了计算研究，计算结果表明，设计方案存在下可道流态复杂及高流速区范围较大等问题，为此比较了三个修改方案，在综合比较水流流态及工程投资的基础上，确定了地涵下游河道连接段推荐方案。推荐方案对于改善下游河道出口至清安河之间的高流速区仍无法有效地改善，需对该区域采取保护措施。

| Abstract: | A study on the lower transient channel flow for the Huai'an culvert project on the flood way of the Huaihe River flowing into sea is carried out by use of a two dimensional numerical flow model. It is found that the flow form is complex and there are some areas of high velocity at the transient channel, which result in local scour. Therefore, three modifications are compared for the selection of the optimal one. Through comparison of the flow and investment,an optimal one is recommended in which the flow is improved significantly. However, the high velocity area can not be avoided,for which some protective measures are suggested. |
