摘  要:
基于1981-2001年水文数据,分析了黄河兰州段河床演变规律;通过动床河工模型试验研究,提出了黄河兰州段泄洪宽度300m的河道整治方案,得到了设计流量为5600m3/s,6500m3/s,7920m3/s,8350m3/s下的相应水位和水面线。在此基础上预测:1)黄河兰州段发生大洪水的可能性仍然存在;2)兰州河段泥沙淤积有加重的趋势。

摘  要:
On the basis of the hydrologic data from 1981 to 2001, the evolution of river bed at Lanzhou section of the Yellow River was analyzed. A river-dredging plan with 300 m of river width was put forwarded by studying the river engineering model experiments. The flood level and water surface profile in different design flood (5 600 m3/s, 6 500 m3/s, 7 920 m3/s, 8 350 m3/s) were gotten with this design. The flood prediction was also proposed.
