摘　　要：闸墙长廊道侧支孔输水系统结构简单、输水效率高、造价低廉,主要适用于中低水头。发展至今,取得了丰富的研究成果,但仍存在一些技术难题。基于国内外大量研究资料,从输水系统布置、消能设施以及船舶系缆力方面对这种输水形式进行全面的评述,并就不足展开了讨论。同时结合经典射流理论,针对侧支孔出流的消能机理,提出了新的研究课题,即侧支孔相向壁面射流流动结构研究,而且对下阶段的研究方向、研究手段和研究内容作了详细说明,以期为后续工作提供参考。The side orifice longitudinal culvert filling and emptying system is mainly applicable to the middle and low water head.It has the characteristics of simple structure,high efficiency and low cost.Nowadays,fruitful achievements have been made.Whereas,there are some difficult problems to study.Based on the large amount of research achievements at home and abroad,the studies on hydraulics are expatiated by layout of the filling and emptying systems,dissipation facilities,in-chamber ship’s mooring forces.Then,some disadvantages are discussed in this paper.Moreover,a new research topic is proposed,combined with jet theory and side orifice flow.It is the studies on the flow structure of the lateral wall jet whose direction is face to face.What is more,hoping to provide reference for further research in this field,the direction,methods and contents in the next stage to be researched have been detailed.
