摘　　要：某枢纽船闸为所处河段通航工程的主要控制性工程,船闸工程的修建将对河道渠化起到重要作用。其闸室规模大、工作水头高、输水能量高,解决输水过程水力学问题是船闸设计的关键环节。为使输水过程船舶与船闸自身安全满足相关要求,通过比尺为130的物理模型试验,对船闸输水过程水力特性、船舶停泊条件及引航道水流条件开展研究。结果表明:在推荐的输水系统布置和阀门开启方式下,各项水力指标均能满足规范和设计要求。A junction lock is the main control project for the navigation engineering of the involved reach,and its construction plays an important role in the channelization of the river.Due to the large scale of the lock chamber,the high working head,and the high water delivery energy,solving hydraulic problems in water delivery is the key link of lock design.To ensure that the ships and locks meet relevant requirements in water delivery,we probe into the hydraulic characteristics,berthing conditions,and flow conditions of approach channels during water delivery on the basis of tests by a physical model with a scale of 130.The results show that under the recommended arrangement of the water delivery system and valve opening mode,all hydraulic indexes can meet the requirements of the codes and design.
