南水北调中线穿黄工程对河势与防洪影响的试验研究

穿黄倒虹吸工程是南水北调中线的关键性和控制性工程,而工程所在河段又是典型的游荡性河道,河床演变情况极其复杂,因此研究工程对河道的影响具有重要意义.通过实体模型试验,对工程修建后对所在河段河势与防洪的影响进行了分析研究,为工程设计提供了科学依据.

Effect of the Yellow River-Crossing Project in the South-to-North Water Project on the River Regime and Flood Control

The Yellow River-crossing project is the key project and also the control project of Middle Route Project (MRP) for South-to-North transfer. The river reach of the project site is a typical braided river and the fluviomorphological process in river is very complicated. So the study on the effect of the project on the riverbed is significant to the project design. This paper analyses the effect of the project on the river regime and flood control by using of physical model. The results provide scientific basis for project design.
