摘　　要：文章以贵港二线船闸为依托,通过建立1∶30比尺的物理模型,对闸室第一道明沟内距闸墙3.70 m处分别增设(高×宽)0.4 m×0.5 m、0.6 m×0.5 m和0.9 m×0.5 m连续消力槛下的水流条件和船舶停泊条件进行研究,对消力槛布置在不同明沟、布置连续或间断消力槛进行对比分析研究。结果表明,在闸室第二道明沟内布置消力槛对水流的分配、调整作用有限,间断消力槛水面交错较连续槛方案布置激烈。几种方案下,在闸室第一道明沟内距闸墙3.70 m处增设0.6 m×0.5 m连续消力槛方案消能效果最优,闸室内水流较均匀,未观测到明显的横向水面比降,水面无局部紊动,船舶的停泊条件较好,也为以后研究同一类型的船闸闸室消能工形式奠定了基础。Based on Guigang second-line ship lock, we established a 1：30 physical scale model to study flow and vessel berthing conditions of 0.4 m×0.5 m, 0.6 m×0.5 m, 0.9 m×0.5 m continuous baffle sill in chamber first open ditch from lock wall 3.7 meters. And we also carried the comparative and analytic research on the baffle sill which layout in different ditch and continuous or discontinuous. The results show that the baffle sill flow distribution effect is limited if it layout in the second open ditch. The surface interleaving under discontinuous baffle sill is fiercer than continuous baffle sill. Between several schemes, the 0.6 mx0.5 m continuous baffle sill in chamber first open ditch from lock wall 3.7 meters scheme is the best. In this scheme, chamber water flow was uniform, we didn＇t observe obvious transverse surface slope and partial turbulent, and vessel berthing conditions were well, it lays the foundation for the study of the same type of lock chamber energy dissipater scheme.
