摘　　要：根据瓯江内河航道规划,已建的外雄船闸过闸船舶由300 t提升到500 t。提出采用设置帷墙格栅消能室对船闸进行改造,在不改变船闸主体结构的条件下满足500 t船舶停泊安全和闸室有效长度不足的问题,在此基础上开展了1∶20的船闸输水系统物理模型试验。研究结果表明:在船闸短廊道输水系统中设置帷墙格栅消能室的形式,不仅能缩短镇静段长度,而且能显著改善闸室内流态,使输水时间、船舶停泊条件均满足设计和规范要求,是一种适用于集中输水系统的消能工布置形式。According to the waterway planning of Oujiang river, the capability of Waixiong ship lock is to be 500 t ships from the original 300 t ones. It is proposed to set a grid stilling chamber in the filling and emptying system to make the effective length and mooring condition of a 500 t ship meet the requirements in Waixiong ship lock, and a 1：20 overall physical model experiment is carried out.The result proves that the grid stilling chamber can not only shorten the length of mitigative section in the ship lock, but also play a very good role in improving the flow regime in ship lock, which makes the filling time and mooring condition of the ship meet the design requirements and norms.The layout of grid stilling chamber is adaptable to the centralized water conveyance system
