摘要
本文对平底板水闸闸堰出流界限及淹没界限进行了探讨，认为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，并给出了闸堰出流淹没界限的判别指标和波状水跃状况下的淹没界限．
his paper reveals the systematical analyses of the submerged limits of orifice and weir outflows of flat lock. The presented distinguishing criteria and formulas for four different flow regimes are expected to have an important significance on the hydraulic engineering design and practice.
