高良涧扩容船闸和二线船闸并列布置，且共用引航道，下游较短范围内引航道与苏北灌溉总渠交汇，其下游引航道水流条件受双线船闸相互泄水及苏北灌溉总渠泄流的影响变得十分复杂。采用二维水流数学模型计算和分析的手段，进行高良涧船闸各种典型水位组合及运行方式下的下游引航道水流条件的研究，针对存在的水力学问题，结合高良涧船闸的特点，提出便捷有效的工程措施--格栅式分隔堤，研究成果可供工程设计和运行管理参考。

Gaoliangjian lock is composed of the expansion shiplock and the second-line shiplock, which is a type. The double lock shares the lower approach channel and confluences with the North Jiangsu Irrigation Canal at a short distance. The flow conditions in the under approach channel are quite complicated due to the emptying courses of the double lock and the North Jiangsu Irrigation Canal. The flow characteristics under different combinations of typical water levels and operation modes are studied by numerical simulation. Considering the lock features, the currently most convenient and effective structural measure, separation levee, is proposed. The results can be used for the lock design and management.
