为了低坎分流墩消能工的推广应用,以低佛氏数(F_r)水流的表面波浪作为研究对象,在揭示低坎分流墩消能工的削波机理基础上,提出了该消能工的体型设计方法,并将其应用在金鸡滩水利枢纽进行物理模拟验证.研究结果表明,利用经验公式设计出的低坎分流墩消能工,消除了低F_r水流水舌摆动的根源,改善了下游水流流态,下游水流表面波浪较小,削波效果显著.研究成果丰富了低坎分流墩消能工技术,为低坎分流墩消能工技术在实际工程中推广应用提供了理论依据.

In order to make diffluent piers with low ridge to be popularized and applied, the surface wave of the low Fr current is chosend as the research object. According to reveal the the weakening wave mechanism of diffluent piers with low ridge, the author put forward its body design method and then confirmed in the Jinjitan project. The result of the research show that the diffluent piers with low ridge based on the experienced formulas can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, the downstream current of water surface wave and wave energy is small and its effect of weakening wave is obvious. This achievement enriches the technology of the diffluent piers with low ridge,which has the important theory value to promote the application of diffluent piers with low ridge into the actual project.
