摘要
通过对黄河山东段 37处引黄渠首涵闸工程的渠首位置、引水高度、口门形状、河闸底高差、河道溜势、防沙设施及分流比等工程要素不同配置的分析 ,探索其对工程引水防沙效能的影响 .黄河山东段渠首工程建设中 ,注重了工程要素的合理配置 ,提高了工程引水防沙效果 .提出今后在渠首工程建设中应注意“三避、两控、一配”问题 .
Based on the analysis of 37 canal head projects on the Yellow River in Shandong Province, a discussion is made on the influences of some engineering factors on the efficiency of water diversion and sediment control, such as the location of canal head, angle of water diversion, entrance shape, elevation difference between river bed and sluice foundation, regime of watercourse, facilities for sediment control, water diversion ratio, etc. During the construction of canal head projects on the Shandong section of the Yellow River, reasonable determination of those factors is emphasized, and the efficiency of water diversion and sediment control is improved. In addition, some problems which should be solved are proposed for future construction of canal head projects.
