摘　　要：在进行西江航运干线桂平二线船闸闸底长廊道输水系统布置和水力分析的基础上,建立了1∶30输水系统整体物理模型,重点研究了34 m宽闸室单根主廊道的闸室水流条件和船舶系缆力。实验研究表明:输水水力特性满足相关规范要求,且设计值与模型实验值吻合较好,经过调整后的闸室出水布置可以满足闸室停泊条件要求,实验达到了预期的目标。Based on the arrangement and hydraulic analysis of lock bottom long-culvert filling ＆ emptying system of Gulping second-lane lock on the main navigation line of Xijiang River, we established a 1：30 overall physical model for the filling ＆ emptying system, and studied mainly the chamber flow conditions and ship＇s mooring force in the 34 m wide lock chamber with single main culvert. The research result reveals that the hydraulic features of the filling ＆ emptying system satisfy the requirements of relevant standards, the design values tally well with the test results, and the arrangement of chamber＇s filling ＆ emptying system after adjustment meets the demand of mooring in the lock chamber. The test has achieved the expected objective.
