摘　　要：高淹没度条件下,水闸出流能力变化较大,其精度关系到水闸和周边工程的正常安全运行。以萧江水闸为例,基于Flow-3D软件,采用RNG k-ε模型和VOF方法建立三维水流数值模型,对高淹没条件下水闸的出流能力进行研究,计算出的上、下游水位关系与物理模型试验结果一致性较好。结合试验成果拟合高淹没度条件下淹没系数的计算公式,公式计算结果与试验值较为吻合。Under the condition of high submerge degree,the flow capacity of sluice changes greatly,and its accuracy is related to the normal and safe operation of sluice and surrounding projects. Taking the Xiaojiang sluice as an example,based on flow-3D software,RNG K-ε model and VOF method were used to establish a 3D Flow numerical model to study the outflow capacity of sluice under high inundation conditions. The calculated relationship between upstream and downstream water level agree well with the results of physical model. The calculation formula of submergence coefficient under the condition of high submergence degree is fitted with the experimental results.
