摘要
针对黄河兰州段河道渠化整治与泄洪的关系 ,在对河道地形、河相关系、造床流量及河床演变规律等分析的基础上 ,通过模型试验研究提出了切实可行的中水整治宽度 2 4 0m、泄洪宽度 30 0m方案 .该方案的实施具有良好的经济。
In accordance with the relationship between flood discharge and the regulation at Lanzhou Section of the Yellow River, based on the analysis of such factors as the topography of the river valley, river regime, bed forming discharge, river bed changes and so on, the scheme of the feasible minimum channel width (300m) of the river training for floods discharging is put forward through experimental study on the model. The model experiment results show that the changes of river configuration are not remarkable and the river training works are suitable for the large floods. Constructive economic, social and environmental benefits will be obtained if this plan is put into effect.
