淹没丁坝动水压力的基本特性及计算方法探讨

Exploration on basic characteristics and calculation method of dynamic pressure on overflow spur dike

    摘要
  • 摘要: 在实验室水槽试验的基础上，对不同槽底（壁）糙率、不同水流压缩比与各级流量、水深条件下的淹没丁坝动水压力进行了探讨。论述了坝体周围动水压力分布的若干基本特性，并根据试验资料，得出平板柱头式不透水直立丁坝动水压力的计算式。

     

    Abstract: In this paper, dynamic pressure formed near overflow spur dike under different channel roughness, different flow constriction proportion, various discharges and depths are studied. Several basic characteristics on pressure distribution at the surface of spur dike are described. According to test data, practical calculation formula(5) applicable to spur dike are presented.
