摘　　要：以贵港二线船闸闸室内双明沟消能工布置为研究对象,建立1:30的整体物理模型。利用多普勒流速测量仪(ADV)、电阻式拉力仪、UBL-2超声波浪/水位采集分析仪等,对闸室内消能后各水力特性进行测量,分析消能特性。试验研究表明:经过优化后的双明沟消能工布置,使船闸闸室内横向水流分配均匀、局部紊动较小,船舶系缆力满足规范要求,闸室内船舶靠泊条件更好。Based on the research of the double open trench energy dissipation work arrangement of Guigang second line ship lock chamber, an overall physical model with the scale of 1：30 was established. By using Doppler velocity measurement instrument （ADV）, resistance type tension meter and UBL-2 ultrasonic wave/water collection analyzer, the hydraulic characteristics of lock chamber were measured, and the energy dissipation characteristics were analyzed. According to the research, it draws a conclusion that the transverse flow inside lock chamber distributes uniformly after the optimization of double open trench energy dissipater layout. The mooring force could meet the requirements of the standards, and the ship berthing condition of lock chamber is also improved.
