摘要
布置于弯曲河道的泵闸工程运行中的水流形态极为复杂,易对建筑物的安全运行、河床冲淤形态、通航水流条件产生不利影响.以上海地区某泵闸工程为例,结合数值模拟,研究比选泵闸布局方案及整流措施.结果表明,泵闸布局优化并设置合理的整流设施可有效改善泵闸运行中的过闸水流流态.
Abstract
The flow pattern of sluice-pump station project arranged in the curved river channel is extremely complex,and it is easy to cause adverse effect on the safe operation of buildings,riverbed erosion and sedimentation patterns,and navigable water flow conditions.Taking a certain sluice-pump station project in Shanghai as an example,combined with numerical simulation,this paper compares the sluice-pump station layout scheme and the corresponding improved meas-ures.The results indicate that optimizing the layout of the sluice-pump station and setting reasonable facilities can effec-tively improve the flow pattern of of the flow through the pump gate.
