浅谈黄河小北干流放淤试验工程关键技术

Discussion on key techniques for experimental warping project of lower north main-stem of Yellow River

通过模型试验对黄河小北干流连伯滩放淤试验工程的各关键技术分别进行了分析。分析表明,采用将放淤闸布设在弯道上段的凹岸、弯道设置溢流堰、淤沙条渠的合理分区和科学调度等措施,可以实现试验工程淤粗排细的目标。

The key techniques for the Liarrbotan experimental warping project of the lower north main-stem of Yellow River are analyzed through the model test concerned respectively. The analysis show that the project target of detaining the coarse and discharging the fine can be got with the related measures, such as placement of the warping sluice on the concave bank of a bending reach; arrangement of the overflow weir on a bending reach and reasonable zoning and scientific control of the desilting channels etc.
