某拦河闸底流消能工消能防冲试验研究

摘要

通过物理模型试验，对某拦河闸底流消能工进行消能防冲试验，测试和分析不同开度下的水闸运行流态、流速分布及上下游水流衔接状况，研究成果可供工程设计参考。%Energy dissipation of hydraulic jump is used to low head and large discharge spillway.This study performed the energy dissipation of hydraulic jump with model test.Some hydraulic characteristics of sluice were given, such as the flow pattern, the velocity distribution and so on.The conclusion can be provided as references to the design and the optimization.
