摘要
根据模型试验成果，阐述了三峡船闸上引航道在船闸充水过程中，重力波流运动的演变规律以及船队系缆力变化过程，论证了船闸输水系统上游取水口布置形式的合理性，研究了在船闸单线充水运行条件下，上游引航道的通航水流条件能够满足设计要求，而双线同时充水则不能满足要求。同时还结合以往的研究成果和工程实践，对于影响重力波流运动的多种控制性因素以及通航水流条件的若干改善措施进行了深入讨论。
Based on the results of hydraulic model test, the evoluting law of the gravity wave and the variations of the hawser forces during the lock filling in the upper approach channel are presented, and the rationality of the entrance layout and structural form of the filling system is verified. it is found that the navigation conditions of the upper approach channel can be satisfied with design during filling of the single line operation, but not in duoble lines. The characters relating to the gravity wave and measures to improve the navigation conditions are discussed in detail. The orientation of study on the navigation conditions in the future is proposed.
