摘　　要：本文基于某电航枢纽整体模型试验,研究船闸导航建筑物实体和透空结构型式对通航水流条件的影响。通过对外导航墙透空的位置,长度,角度和高度的变化对整个引航道以及口门区水流条件的变化情况作深入研究分析。试验得出,当透空比为0.4,透空孔轴线与导航墙轴线顺水流方向交角成30°(顺时针方向)时,有利于减少引航道内的泥沙淤积,改善了引航道口门区的通航水流条件。The paper studies the influence of solid mass and permeable structure of navigation lock guidance structure to navigation flow condition based on integral model test of power and navigation complex.The approach channel and the flow condition in the entrance is studies through the variation of position,length,angle and height of outward guidance wall permeable body.The result indicates that the permeable ratio 0.4,the included angle 30°between permeable opening axis and flow direction,it is advantageous to reduce the sediment deposition in the navigation channel and to ameliorate the flow condition in the approach channel.
