摘　　要：随着小浪底水库的投入运用,进入黄河下游的水沙条件发生很大变化,因部分河道整治工程与新的水沙关系不匹配,下游河势极易发生调整,使得现有流路与规划流路不一致,一些河段出现畸形河势。通过开展黄河下游河道综合治理工程推荐方案模型试验研究工作,来检验工程续建后对河势的影响。对比工程现状方案和拟建方案的试验结果发现,拟建方案不利河势的调整部位较现状方案多,拟建方案有利于河势向规划流路调整,河势基本稳定。As the Xiaolangdi Reservoir was put into operation,the water and sediment conditions entering into the lower Yellow River have been changed greatly.Because some river training projects do not match the new water and sediment relations,the river regime in the lower reaches is very easy to be adjusted,which makes the existing flow path inconsistent with the planned one and abnormal river regimes have e⁃merged in some sections of the river.In order to test the influence of the continuation of training projects to the river regime,the model test of the recommended scheme of the comprehensive treatment project in the lower Yellow River was carried out.By comparing the test results be⁃fore and after the continuation of the project,it is found that the proposed scheme has more adjustment parts to the unfavorable river regime than the current scheme.The proposed scheme is conducive to the adjustment of the river regime of the planned flow path and basically stabi⁃lizing the river regime.
