Investigating the effect of spacing on the effect of staggered-slip permeable spur dike on flow mitigation can provide a theoretical basis for the design of modern shore protection projects. The CCHE2D software was used to conduct a two-dimensional numerical simulation study of the solid flume model in the Xinqiman section of the Tarim River. And then the effect of different spacing on the water surface line, flow velocity and bed shear stress distribution in the upstream permeable spur dike area under the action of staggered-slab permeable spur dike was analyzed. When the relative dam length ratio is 0.21, and the inflow and dam length remain unchanged, the larger the spacing, the better the uniformity of flow and velocity behind the upstream permeable spur dike, and the lower the value of water level and shear stress in the riverbed. When the spacing is 5 times the effective dam length, the flow velocity, water level and riverbed shear stress behind the upstream permeable spur dike tend to be stable. The results of the study can improve the theory of flow mitigation effect in the action area of inserted permeable spur dike.

探究间距对错口插板透水丁坝缓流效果的影响,可为现代护岸工程的设计提供理论依据。使用CCHE2D软件对塔里木河新其满河段实体水槽模型进行二维数值模拟研究,分析了不同间距错口插板透水丁坝对上游透水丁坝作用区水面线、流速、河床切应力分布的影响规律。结果表明,当相对坝长比b/B=0.21,且在来流量、坝长等因素不变的情况下,透水丁坝间距越大,上游插板透水丁坝坝后缓流及流速均匀性越好,水位雍高值逐渐减小且河床切应力呈减小趋势。当间距为5倍有效坝长时,上游插板透水丁坝坝后流速、水位及河床切应力均趋于稳定。研究结果可完善插板透水丁坝作用区缓流效果理论。

探究间距对错口插板透水丁坝缓流效果的影响,可为现代护岸工程的设计提供理论依据。使用CCHE2D软件对塔里木河新其满河段实体水槽模型进行二维数值模拟研究,分析了不同间距错口插板透水丁坝对上游透水丁坝作用区水面线、流速、河床切应力分布的影响规律。结果表明,当相对坝长比b/B=0.21,且在来流量、坝长等因素不变的情况下,透水丁坝间距越大,上游插板透水丁坝坝后缓流及流速均匀性越好,水位雍高值逐渐减小且河床切应力呈减小趋势。当间距为5倍有效坝长时,上游插板透水丁坝坝后流速、水位及河床切应力均趋于稳定。研究结果可完善插板透水丁坝作用区缓流效果理论。

Investigating the effect of spacing on the effect of staggered-slip permeable spur dike on flow mitigation can provide a theoretical basis for the design of modern shore protection projects. The CCHE2D software was used to conduct a two-dimensional numerical simulation study of the solid flume model in the Xinqiman section of the Tarim River. And then the effect of different spacing on the water surface line, flow velocity and bed shear stress distribution in the upstream permeable spur dike area under the action of staggered-slab permeable spur dike was analyzed. When the relative dam length ratio is 0.21, and the inflow and dam length remain unchanged, the larger the spacing, the better the uniformity of flow and velocity behind the upstream permeable spur dike, and the lower the value of water level and shear stress in the riverbed. When the spacing is 5 times the effective dam length, the flow velocity, water level and riverbed shear stress behind the upstream permeable spur dike tend to be stable. The results of the study can improve the theory of flow mitigation effect in the action area of inserted permeable spur dike.
