菏泽黄河河段包括游荡性河段和过渡性河段,河道宽、浅、散、乱,主槽摆动频繁,滩区面积大,滩内居住人口多,由于泥沙大量淤积河道,主河槽淤积严重,已形成“槽高、滩低、堤根洼、堤外更洼”的“二级悬河”的危险局面。虽然经过堤防加固和滩区村台等工程建设,但由“二级悬河”带来的问题仍不能得到根本解决,防洪形式仍很严峻。针对这些问题,结合菏泽“二级悬河”形势和滩区情况,为加快“二级悬河”治理研究,拟采取人工淤滩措施,包括自流放淤和机淤抽沙等,探讨治理“二级悬河”的新途径,从根本上解决“二级悬河”的不利形势。 The Heze Yellow River includes the wandering and transitional sections of the river. The channels are wide, shallow, scattered and chaotic. The main channel swings frequently. The area of ​​the beach area is large and the population in the beach is large. Due to siltation of sediment, the main channel is silted Serious, has formed a “trough high, beach low, embankment depression, embankment more depression,” the “two hanging river” dangerous situation. Although it has been reinforced by dike and construction of beach and village committees, the problems caused by the “secondary hanging river” still can not be fundamentally solved, and the form of flood control is still very serious. In view of these problems, combined with Heze “secondary suspended river” situation and the beach area situation, in order to speed up the “secondary hanging river” governance research, intends to take artificial silt measures, including self-flow sedimentation and silt pumping sand, discuss governance “two Class hanging river ”a new way to fundamentally solve the“ secondary hanging river ”unfavorable situation.
