黄河口清水沟流路治理工程实践及建议

Practice and Advice of Qingshuigou Channel Harnessing Project in Yellow River Estuary and Some Suggestions

分析了黄河口清水沟流路工程治理实践与效果,结果证明工程效果明显,尾闾河道萎缩减缓、稳定性增强、拦门沙危害程度明显减弱、流路使用年限延长。黄河下游水沙过程变异使河口演变出现了新问题,未来黄河口治理应加强原型观测与科学研究,同时继续实施挖河疏浚、河道整治及口门扰动疏浚等有效工程措施。

Using the method of data analyzing and theoretical discussion, the practice and effect of Qingshuigou channel harnessing project was analyzed deeply. The result of research shows that, the effect of Qingshuigou channel harnessing is obvious, the atrophy of tail channel becomes slower, the stability of tail channel is increased, the harm of sandbar is alleviated, and the service life of Qingshuigou channe is prolonged. The variation of flow and sediment happened in the lower Yellow River, so the new problems took place in the Yellow River Estuary. In future, the harnessing of Yellow River Estuary should strengthen prototype observation and research, at same time dredging and harness of channel should be continue.
