【摘要】 到目前为止,对泡漩水险滩的整治主要采取现场观察、工程实践经验和河工模型试验相结合的办法,因此,泡漩水模型试验的相似性显得尤为重要.笔者通过不同尺寸的水槽概化模型试验,对泡漩水的相似性进行了研究,试验结果表明,正态模型泡漩水流的泡高、水深、流速和流态是相似的.更多还原

【Abstract】 Up to now,ponding and vortex flow critical shoals are regulated by site ob servation and hydraulic model.Therefore,the similarity of model tests for pondin g and vortex is very important.In thi s paper,the similarity of ponding an d vortex has been investigated by model tests with different size in flumes.Test results show that the height,water depth,flow velocity and flow pattern of ponding and vortex flow are similar in undistorted model.更多还原
