摘要
水流与群桩间的相互作用是一个较为复杂的问题。此文分析了水流与群桩相互作用的机理,并提出利用群桩阻力损失和群桩的冲刷深度来表达它们间的相互作用。水槽动床试验表明,群桩绕流阻力损失和桩的冲刷深度与桩间距和纵向排数的关系较为密切。
Interaction between water flow and the group of pile is a complex problem. In this paper, the interaction mechanism was analyzed on the basis of hydraulic engineering, which can be expressed by resistance and scour of group piles. Finally, it was found by experiments in a flume that resistance and scour of group piles have close relations with pile spacing and the amount of pile row.
