今年黄河下游在以防洪为主的前提下,正式着手进行了河道整治工程,为逐步同灘縮槽,控制河势变化创造条件。这对今后全面整治有其重大的指导意义。由于这是一项新的工作,我们的经验不足,因此,無論在工程布置上、工程措施上以及修筑方法上都是摸索进行的。河南境内的黄河属于游蕩性的河道,歧流散布,宽淺多变,河槽左右摆动,極不稳定。这样的复杂河道,欲在短期内一举完成河道湖渠 This year, under the precondition of mainly flood control, the lower reaches of the Yellow River formally embarked on river improvement works to create conditions for gradual reduction of troughs and control of river regime changes. This has great guiding significance for the comprehensive improvement in the future. Since this is a new job, our experience is not enough. Therefore, both the engineering arrangement and the construction methods are explored. The Yellow River in Henan Province is a wandering river, which is experiencing a wide range of fluctuating currents and swings around the river channel. It is extremely unstable. Such a complex river, in one fell swoop to complete the river channel in a single stroke
