摘　　要：消能防冲计算是水闸工程设计中的重要环节,消力池、海漫段、防冲槽等消能防冲设施的结构尺寸都需要通过计算确定。水闸设计规范给出了相应的消能防冲计算公式。结合工程实例,从计算水位组合的选取、河道不冲流速及允许流量的计算、闸门开度及过闸流量的确定、消能防冲计算过程、消能防冲设施布置等几个方面对水闸工程中的消能防冲计算及消能防冲设施设计进行了简要介绍。The calculation of energy dissipation and scour prevention is an important part in sluice design.The structural dimensions of energy dissipation and anti scour facilities such as stilling basin,apron section and anti scour groove need to be determined by calculation.The corresponding calculation formula of energy dissipation and anti-scour is given in the design specification of sluice.A brief introduction is made with an example of engineering about the selection of calculation of water level combination,calculation of non scour velocity and allowable flow of river channel,determination of gate opening and sluice discharge,calculation process of energy dissipation and anti scour,layout of energy dissipation and anti scour facilities.
