基于SCS模型的双桥浜排涝泵站规模计算

Calculation of drainage capability of Shuangqiaobang pump station based on SCS model

根据常州市城市河道排涝标准,在设计典型暴雨的情况下,基于SCS模型对双桥浜区域的产汇流过程进行模拟,并以此为依据模拟了泵站不同排水规模情况下水位的变化过程。模拟结果表明:双桥浜泵站现有的排涝能力偏低,不能满足本地区防洪除涝的要求,合适排涝规模为5.00 m3/s。

According to river drainage standard of Changzhou city and Under the condition of typical rain- storm , the runoff process of Shuangqiaobang area was simulated based on SCS model . The variation process of water level in pump station is also simulated under the condition of different drainage capabili- ties. Simulation results show that the existing drainage capability of Shuangqiaobang pump station is low and cant meet the requirements of the region＇s flood control and waterlogged. The suitable scale of drain- age is 5. 00 m3/s.
