摘  要:淮河中游行洪区是中游防洪体系的重要组成部分,现有行洪区多,启用频率高,行洪效果差,经济损失大。进行进一步治淮,将对淮河中游行洪区进行调整,调整后其行洪能力的确定关系到中游河道整治工程布局和行洪区优化调度。影响行洪区行洪能力的主要因素有行洪区几何形态、进退洪闸规模与布置以及进退洪闸间河道水力条件等。该文采用水动力数学模型及实体模型(河工模型与水工模型)等手段,对淮河干流正阳关至浮山段仍保留的5个行洪区行洪能力进行计算与试验验证,确定了5个行洪区规划条件下的泄流能力。The flood-flowing zone of the Middle Reach of the Huihe River is one of important components of the flood protection system of the Huihe River. The existing flood-flowing zones of the Huihe River consist of a lot of individual flood-flowing zones which are often used for flood flowing. However, the existing flood flowing zones are neither efficient nor economic. Further river engineering work for the Huihe River requires regulation of the flood-flowing zones of the Middle Reach of the Huihe River. After regulation of the flood-flowing zones, the discharge capacity of the flood-flowing zones of the Middle Reach of the Huihe River will affect the reallocation of river engineering work and the optimal allocation of flood-flowing zones. Key factors affecting the discharge capacity of the flood-flowing zones are: Geometry of flood-flowing zone, size and layout of the inlet-and-outlet gates for flood storage, hydraulic parameters of the inlet-channel to the flood-flowing zone and outlet-channel fromthe flood-flowing zone, etc. In this paper, both hydrodynamic simulation and physical experiments have been carried out to study the discharge capacity of 5 flood-flowing zones along the river reach from Zhengyangguan to Fushan of the Huaihe River. The results of the calculation and verified test show that the discharge capacities of these 5 flood-flowing zones in regulation have been determined.
