山东黄河东明段二级悬河治理方案研究

Research on the Treatment Scheme of the Secondary SuspendedRiver in Dongming Section of the Yellow River in Shandong

摘要:

近年来,黄河泥沙持续淤积,导致下游河道"二级悬河"不断加剧,较大及以上洪水极易沿着大堤顺流而下，严重时甚至会引发滚河現象,因此对二级悬河进行治理是非常必要且紧迫的。基于上述現象,文中提出了堤河淤填与防护坝两种方案治理措施,并对治理效果、工程建设投资、移民征地、料场来源、工程管理5个方面进行对比分析。综合分析结果表明,对山东黄河东明段二级悬河采用堤河淤填治理方法，既经济合理又技术可行。

Abstract:

In recent years, the continuous silting of sediment in the Yellow River has intensified the "secondarysuspended river"in the lower reaches. Floods of moderate or larger scale are prone to flow downstream along the dykes,and in severe cases, even river migration may occur. Therefore, the treatment of the secondary suspended river isextremely necessary and urgent. Based on the above phenomenon,this paper proposes two treatment schemes: dykechannel hack-filling and prolective dam construction. A comparative analysis is conducted from five aspects: treatmenteffect, project construction investment, resettlement and land acquisition, material source, and project management.Thecomprehensive analysis results show that the dyke channel back-filling method for the treatment of the secondarysuspended river is both economically reasonable and technically feasible.
