摘要
水力插板透水丁坝是一种新型丁坝。本文以水力插板透水丁坝群、井柱桩透水丁坝群和实体丁坝群为研究对象进行动床模型试验。用测针测量各丁坝群附近地形,并用Surfer8.0绘制各丁坝群附近的地形图。结果表明:水力插板透水丁坝群累积效应减少局部冲刷的性能最好,其次是井柱桩透水丁坝群,实体丁坝群性能最差。最后详细地分析了各丁坝群减少局部冲刷差异性产生的机理。
Hydraulic flashboard permeable spur dike is a new kind of spur dike. the paper conducted the moving bed model test by taking the three kinds of spur dike group such as types of hydraulic permeable flashboard,well column pile permeable and entity as research object. It surveyed the terrain by arrow and used surfer 8.0 to draw topographic map near dikes. The result indicated that the cumulative effect of reducing local scour by hydraulic flashboard permeable spur dike is the best, and in turn is permeable pile spur dike. The performance of entity spur dike is the worst. Finally, the paper detailedly analyzed the differencial mechanism of reducing the local scour of spur dikes group.
