摘要
交错布置的涉河设施普遍阻水比较大,影响河道行洪.但国内涉及交错布置阻水设施对河道水流内部水力特性影响的研究相对较少.采用一维、二维水力模型联合应用的方式进行河道内交错布置阻水设施对洪水演进的影响研究,分析桥墩对河道行洪的流态改变、壅水程度,并针对性地提出工程补救方案,保障区域的行洪安全.该研究成果不仅能够为工程设计提供有利的水力条件支撑,还可为后续类似工程提供理论经验.
Abstract
The staggered river crossing facilities generally block the water and affect the flood flow.However,there are relatively few studies on the influence of staggered water blocking facilities on the internal hydraulic characteristics of river flow in China.The influence of staggered arrangement of water blocking facilities on flood evolution was studied by the combined application of one-dimensional and two-dimensional hydraulic models.The change of flow pattern and degree of backwater caused by bridge piers were analyzed,and the engineering remedy scheme was put forward to ensure the flood safety of the region.The research results can not only provide favorable hydraulic conditions for engineering design,but also provide theoretical experience for subsequent similar projects.
