摘　　要：某船闸上游引航道在枢纽运行初期和后期最低通航水位为135.0 m和145.0 m时,航道水深分别为5.0 m和6.0 m,均属浅水限制性航道。双线船闸灌水将导致引航道中发生复杂的非恒定流长波运动,并影响船舶停泊和航行安全。本文研究的目的在于试验测定原设计布置和工况下长波运动特性和船队停泊、航行条件,针对波动特征值和缆力值,初步研究改善措施,为前期技术方案设计和后期运行管理提供参考。When the lowest navigable water level is 135.0 m and 145.0 m,the water depth of the upstream ap⁃proach channel of a ship lock is 5.0 m and 6.0 m respectively,which belong to shallow restricted channel,the long-wave motion of unsteady flow in the approach channel will be caused by the filling of double-line lock,which will affect the safety of ship berthing and navigation.The purpose of this paper is to test and determine the characteristics of long-wave motion and the conditions of Mooring and navigation of the fleet under the origi⁃nal arrangement and working conditions,it provides the reference for the early stage technical scheme design and the later stage operation management.
