摘要
以宁夏吴忠地区金积供水工程输水明渠为例,验证了垂向二维模型CE-QUAL-W2模拟输水明渠冰盖生消的可行性。在此基础上,构建了南水北调京石段输水明渠冰盖模型,模拟了典型气温过程中冰盖在不同输水流量及入流温度条件下的发展过程,模拟结果表明以上因素对冰情的发展有不同程度的影响。
Taking the canal of water supply project in Jinji Wuzhong, Ningxia as an example, the paper vertified the viabiliyy of CE-QUAL-W2 to simulate the growth and melt of ice cover. Above this, the model of Beijing Shijiazhuang section of the Middle Route of South-to-North Water Diversion Project was constructed. The ice cover thickness process was analyezd considering the change of inflow and the temperature of inflow. The results show that inflow and the temperature of inflow affect the ice cover process in some degree.
