| 摘 要： | 当水流通过泄水建筑物的收缩、扩散和弯道段时,将会产生一系列较强的冲击波.冲击波的产生使得水流的动量横向分布很不均匀,恶化了水流流态,给工程带来不利影响.在分析了陡槽急流冲击波的扰动特性的基础上,提出了几种消减弯道急流冲击波、直槽收缩连接段急流冲击波以及宽浅陡槽急流冲击波的方法.这些措施在实际工程中得到应用已获得了良好的效果.

| Abstract: | A series of strong shock waves will be produced when water current passes those special sections, such as constringent section,proliferation section and curved section in discharge structures. And the wave makes the water current asymmetric in transverse distributing of momentum, causes the flow pattern worse, and brings engineering disadvantageous influence. Based on the analysis on the characteristic of disturbance of rapid flow shock wave in sloping channel and some methods of avoiding the shock wave influence and improving flow pattern are introduced, these measures have gotten good results in actual engineering. |
