摘要
为保障拟建慈江化子泵站下游弯道凸岸重点建筑安全,采用经实测资料验证后的数学模型,对化子泵站下游河段的流态及流速分布情况进行了数值模拟研究。通过数值模拟得到了不同水位、流量、机组运行方式组合条件下,化子泵站运行时下游弯道处水动力特性变化规律,给出了不同组合条件下下游弯道处最大流速及出现位置,分析了最大流速与泵站出流流量、运行方式、下游水位之间的关系。
For the safety of the hydraulic structure at the outer river bend downstream the proposed project of Cijiang Huazi Pump Station,a numerical model was set up and calibrated with measured data. The model was used to investigate the flow pattern and the velocity distribution at the river bend under different combinations of the designed water levels,outlet discharges and the operations of the pump station. The general law- of the hydrodynamic characteristics of this reach was obtained the value of the maximum velocity and the position of maximum velocity was identified. The relationship among the maximum velocity,the outlet discharge from the pump station,the operations of the pump station,and the water level at downstream was analyzed.
