摘　　要：针对通航建筑物下游引航道口门区复杂流场的现场观测难题,发明了高精度的水流流速、流场测试方法,准确获得不同流量工况下景洪升船机下游引航道口门区的横向、纵向及回流流速,揭示带透水导墙的引航道口门区流场结构特征,为升船机船舶通航安全评价、航路航法优化等通航管理提供重要依据;并将原型观测与模型试验结果进行对比分析,针对通航水流条件模型试验及船舶通航安全评估提出建议,可为相关研究提供参考。In order to solve the problem of the prototype observation for the complex flow field at the entrance area of downstream approach channel of navigation structures,we invent a new method to measure the flow velocity and field more precisely,and obtain the transverse velocity,longitudinal velocity and reflux velocity at the entrance area of the downstream approach channel of the ship lift under different flow conditions and reveal the characteristics of the flow field at the entrance area of the approach channel with permeable guide wall,which provides an important basis for navigation safety evaluation of ship lift and optimization of route and navigation method.Comparing the results of prototype observation and model test,we put forward some suggestions for the model test of navigable flow condition and the evaluation of ship navigation safety,which can provide reference for related research.
