摘　　要：利用ADV等先进的量测仪器,通过物理模型实验对高水头船闸闸室明沟和盖板消能工的消能效果进行比较。在相同实验条件下,通过对流速分布、剩余比能和水面波动等参数的对比和消能特性的分析表明:明沟消能效果优于盖板消能。明沟消能工结构简单,在我国应用不多,建议对其加强进行研究及应用。Using advanced measurement equipments such as ADV,the energy dissipation effect of open ditch energy dissipater and cover plate energy dissipater is compared by means of physical model experiments.Through analyzing energy dissipation characteristics and comparing those parameters,for instance velocity distribution,remaining energy and water surface fluctuations,the results indicate that the energy dissipation effect of open ditch energy dissipater is superior to the cover plate energy dissipater under the same condition.The open ditch energy dissipater structure is simple and it is not popular in current China.It is recommended to strengthen its further research and application.
