赣江万安二线船闸输水系统水力学模型试验研究

万安二线船闸工作水头和一次输水过程能量均居世界单级船闸前列,输水系统设计直接关系到工程设计成败。根据《船闸输水系统设计规范》和类似工程经验,结合水力计算,设计优化了适合万安二线船闸的闸墙主廊道、闸室中部垂直立体分流、闸底四纵支廊道两区段出水、明沟消能的输水系统形式。通过比尺为1∶30的整体物理模型试验,研究了所设计输水系统的水力特性。成果表明:万安二线船闸所采用的输水系统整体设计是合理可行的,输水时间、船舶停泊条件、进出水口及引航道水流条件等各项水力指标均满足设计和规范要求。

Hydraulic model test and study on filling and emptying system of Wan'an 2nd lane lock on the Ganjiang River

The water head and the flow energy of Wan’an 2 nd lane lock are all among the highest single-step locks around the world. The filling and emptying system design is the key part of the lock design. According to the design code for filling and emptying system of ship locks and based on analyzing a great number of references,combined with the hydraulic simulation, the filling and emptying system with wall culverts, vertical divider, inchamber 4 manifolds of Wan’an 2 nd lock is put forward and optimized. The results of the model test( scale 1∶30)indicate that the layout and design of the filling and emptying system of Wan’an 2 nd lane lock is reasonable and doable,thus the filling( emptying) time, vessel’s berthing conditions, and flow conditions around the inlets and outlets and in the approach channels are all satisfying the requirements of the code and design.
