Abstract

Abstract: Up to now，ponding and vortex flow critical shoals are regulated by site observation and hydraulic mode1． Therefore， the similarity of model tests for ponding and vortex is very important．In this paper， the similarity of ponding and 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 alre similar in undistorted mode1．

Key words: undistortedmodel, pondingandvortexflow, similarity

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．
