| 摘 要： | 通过对平底板水闸闸堰出流界限及淹没界限的探讨，结果表明：闸孔出流及堰流的界限不仅与闸门的相对开度有关，而且还受水闸上下游水位的影响，提出了闸堰出流淹没界限的判别指标及波状水跃状况下的淹没界限

| Abstract: | This paper systematically analyses the submerged limits of orifice and weir outflows of flat lock and presents the distinguishing criteria and formulas for the four flow regimes. These criteria and formulas have an important significance on the hydraulic engineering design and practice usage. |
