丁坝群 meaning in Chinese
groin system
Examples
- Three kinds of permeable pile dikes with different seepage rate are tested , and effect of flow control is basically the same with the spur dike ,
试验的三种透水率桩坝，其导流效果与实体丁坝群的基本相同，并未因部分透水及形态不同而使其控导作用明显减弱。 - The outline tests on the alignment of spur dikes in the flume with repeated tidal flow were carried out based on the alignment of the regulation structures in the north trough of the deep waterway in the yangtze estuary
摘要结合长江口深水航道治理二期工程北槽中整治建筑物的布置形式，在潮汐往复流水槽中进行了丁坝群不同布置形式的概化试验。 - Test results show that spur dikes aligned along a single bank in the deep water zone have more effects on the adjustment of the bed topography of the wide - shallow river than in the shallow water zone ; alignment of spur dikes along both banks can effectively adjust the planimetric position of deep - water zone ; and a reasonable widening rate of the regulation line in the estuary can readjust the variation of the average water depth along the river
试验结果表明，在深水区的单侧丁坝群对宽浅河床地形的调整作用大于浅水区；双侧丁坝群的联合作用能调整深水区的平面位置；合理地选择治导线的放宽率，能有效地调整深槽平均水深的沿程变化。 - Through flume experiment and numerical simulation , preliminary work on computation of water surface profile in regulation river reach , numerical simulation of flow with single spur dike in flume , and 3 - d numerical solution of flow around spur dikes group are carried out in this paper
本文通过模型实验和数值模拟相结合的研究方法，在整治河段一维水面曲线计算，单丁坝绕流数值模拟，紊流数学模型在航道整治工程中的应用以及丁坝群附近水流的三维流动特性等方面做了一些初步研究。
