韩庄双线船闸通航水流条件改善措施

韩庄拟建复线船闸和一线船闸共用引航道,船闸灌、泄水过程中下游引航道中产生非恒定流,上游韩庄节制闸、老运河节制闸泄洪期间韩庄船闸下游水流流态更加复杂。采用国际上通用的MIKE21水动力模型,研究了泄洪期间韩庄船闸下游引航道、靠船墩、口门区的纵向流速、横向流速及回流分布情况,并按照《船闸总体设计规范》相关要求,针对泄洪期引航道的水力学问题,提出了改善水流的有效工程措施。

Improvement measures of navigation flow condition of Hanzhuang double way locks

Hanzhuang double way locks shares the approach channel and its filling and discharging will generate unsteady flow in the downstream approach channel.During flood discharge of Hanzhuang sluice and the old canal sluice,the flow conditions of approach channel are more complex.This study uses international general MIKE21 hydrodynamic model to study the longitudinal velocity,transverse velocity and reflux distribution of approach channel,waiting area and entrance of approach channel of the downstream Hanzhuang double way locks.In accordance with the Code for Master design of shiplocks,to solve the problem of hydraulic during flood discharge,this study proposes effective engineering measures for improving the flow conditions.
