摘　　要：为解决北河桥闸工程下游消能问题,采用水工断面模型试验的方法对其消能工程进行优化。试验表明,原设计方案闸孔下泄水流在消力池内未形成淹没水跃,不满足设计提供的闸门调度运行要求。考虑工程安全并结合类似工程,模型推荐方案为:在原设计方案消力池内加设消能墩,水流在消力池中形成强迫水跃。To solve the downstream energy dissipation of Beihe bridge gate project, a sectional hydraulic model experiment was conducted to optimize the energy dissipation technology. The experimental results showed that： in the original design scheme, the discharged water flow could not meet the design requirement for bridge gate operation, for the submerged hydraulic jump did not appear in the stilling basin. Considering engineering safety and similar projects, the recommended model program was proposed as follows： adding energy dissipation pier in the stilling basin in the original design scheme, and making the water flow form the forced hydraulic jump.
